CBSE Class 12 Physics — 25 Most Expected Questions 2027 | Padhaao Blog

In short: Nobody outside CBSE knows the exact 2027 Physics questions, so this list ranks 25 question types by evidence: the 2026-27 paper design (33 questions, 70 marks, five sections), what teachers reported about the February 20, 2026 board paper, and the chapters that carry marks. The 2026 paper leaned on derivations and multi-step numericals, and teachers called it lengthy. Our SQP-based Physics list covers the sample paper. This one adds what the real board paper showed. Treat it as a practice priority list, not a leak.

Last updated: October 28, 2026. The 2027 date sheet is not out yet. The paper design below is the 2026-27 sample paper design.

What I could not verify

Item	Status
Marks for every unit in 2026-27	I could confirm only three units. EdexLive's 2026-27 breakdown gives Electrostatics 16 marks, the Magnetic Effects of Current and Magnetism block 17 marks and Electronic Devices 7 marks. Check the full list in the CBSE syllabus PDF
Exact derivations asked in Section E in 2026	Coverage names the chapters (Electrostatics, Ray Optics, EMI and AC), not the individual derivations
Which optics case study was asked	Reports conflict (see below)

What the 2026 Paper Showed

Section	What was reported	Source
A: MCQs and assertion-reason	Moderate. A mix of memory-based and conceptual items. One principal said the MCQs needed more calculation than expected	Times Now, NDTV
B: 2 marks	Questions on Nuclei, Dual Nature, Wave Optics and Moving Charges (a torque question). Mostly easy. The torque question could trouble below-average students	Times Now, NDTV
C: 3 marks	Gauss's law for a plane sheet, a Wheatstone network, a dielectric inserted in a capacitor, p-n junction formation, and ray diagrams. Multi-step numericals on electrostatic potential, a semiconductor diode circuit and total internal reflection	Times Now, NDTV
D: case studies	Galvanometer and photoelectric effect. Moderate and conceptual	Times Now, NDTV
E: 5 marks	Derivations from Electrostatics, Ray Optics, and EMI and AC. Scoring for students who had practised previous derivations	Times Now, NDTV
Overall	Several derivations made the paper lengthy. Many questions resembled previous year questions. Some questions came from NCERT solved examples	Times Now, NDTV
Language	Clear and straightforward	NDTV

Where reports disagree

Topic	Report A	Report B
Difficulty	NDTV: teachers called it easy to moderate. Times Now: easy, but lengthy	NDTV (Udaipur teacher): moderate to difficult and fairly lengthy. Lancers Army Schools HOD: above moderate
Case study	Times Now and NDTV: case studies on the galvanometer and the photoelectric effect	NDTV (Delhi principal): the case study from Optics was relatively tough
Section A order	Times Now (a student): Section A was tougher in Set 3	NDTV (Udaipur teacher): students had less time for Section A because of the length, and many attempted it last

I cannot settle these from the official papers. The consistent points are that the paper was long, derivations and numericals dominated, and it rewarded practice.

Section A: MCQs and Assertion-Reason (16 Marks)

#	Expected question	Evidence
1	Calculation-based MCQ on Electrostatics, Current Electricity or Optics	2026 paper (MCQs needed more calculation than expected)
2	Assertion-reason on a concept such as the nature of an electric field, magnetic field lines or the photoelectric effect	2026 paper (moderate, conceptual)
3	Direct, memory-based MCQ on a definition, unit or law	2026 paper (a mix of direct and conceptual)

How to answer

Situation	What to do
Calculation MCQ	Write the formula, substitute with units, and check the order of magnitude. Do not use the options to guess
Assertion-reason	Test the assertion and the reason separately. Then ask whether the reason explains the assertion
Time	Skip a long MCQ and return to it. The 2026 paper was long, and one teacher said many students attempted Section A last

Section B: Two-Mark Questions (10 Marks)

#	Expected question	Evidence
4	Torque on a current-carrying loop in a magnetic field	2026 paper (Moving Charges, torque)
5	Nuclei: mass defect, binding energy or a decay law	2026 paper
6	Dual Nature: photoelectric effect, work function or de Broglie wavelength	2026 paper
7	Wave Optics: fringe width, Huygens' principle or the condition for interference	2026 paper

Answer format (all examples are illustrative)

Question	What to write
Torque	The formula is torque = N I A B sin(angle between the normal and the field). Example: N = 100, I = 2 A, A = 0.01 m², B = 0.5 T, normal perpendicular to the field gives torque = 100 x 2 x 0.01 x 0.5 = 1 N m
Nuclei	Energy released = mass defect in u x 931.5 MeV. Example: a mass defect of 0.03 u gives about 27.9 MeV
Photoelectric effect	Maximum kinetic energy = photon energy minus work function. Example: 400 nm light has about 3.1 eV (using hc = 1240 eV nm). With a work function of 2.0 eV the maximum kinetic energy is about 1.1 eV
Wave optics	Fringe width = wavelength x D / d. Example: 600 nm, D = 1.5 m, d = 0.3 mm gives 3 mm

Section C: Three-Mark Questions (21 Marks)

#	Expected question	Evidence
8	Use Gauss's law to find the field of an infinite plane sheet of charge	2026 paper
9	A Wheatstone bridge network: balance condition and an unknown resistance	2026 paper
10	A dielectric slab inserted in a capacitor: change in capacitance, charge, potential and energy	2026 paper
11	Explain how a depletion layer and barrier potential form in a p-n junction	2026 paper
12	Ray diagram and magnifying power of an optical instrument	2026 paper
13	Multi-step numerical on electrostatic potential or potential energy	2026 paper
14	Numerical on a semiconductor diode circuit	2026 paper
15	Numerical on total internal reflection and the critical angle	2026 paper

Answer format (examples are illustrative)

Question	What to write
Plane sheet	Draw a cylindrical Gaussian surface. Flux comes out of two end faces, so E x 2A = sigma A / epsilon-zero, giving E = sigma / (2 epsilon-zero)
Wheatstone bridge	At balance P/Q = R/S. If P = 10, Q = 20 and R = 15, then S = 30 ohm
Dielectric insertion	Say clearly whether the battery stays connected. Example with the battery disconnected: C0 = 10 microfarad charged to 100 V stores 0.05 J. Inserting K = 5 makes C = 50 microfarad, keeps Q at 1 mC, drops V to 20 V and drops the energy to 0.01 J
p-n junction	Diffusion of carriers across the junction leaves immobile ions. The depletion layer grows until drift balances diffusion. Mention the barrier potential and include a labelled diagram
Optical instrument	Telescope in normal adjustment: magnifying power = fo / fe and tube length = fo + fe. Draw the ray diagram with the final image at infinity
TIR	Critical angle: sin(ic) = 1/n. For n = 1.5, ic is about 41.8 degrees
Diode circuit	State whether the diode is forward or reverse biased. Example with an ideal forward-biased diode, 5 V and 1 kilo-ohm: current = 5 mA

Teachers described Section C theory as easy and expected, and the multi-step numericals as testing analytical skill. Times Now also quoted a student who found Section C lengthy.

Section D: Case-Study Questions (8 Marks)

#	Expected question	Evidence
16	A passage on the moving coil galvanometer, with sub-questions on torque, sensitivity and conversion	2026 paper
17	A passage on the photoelectric effect, with sub-questions on threshold frequency, stopping potential and kinetic energy	2026 paper
18	A passage on an optical device or optical phenomenon, with sub-questions	Reports conflict. One principal called the 2026 Optics case study tough

Answer format (examples are illustrative)

Galvanometer conversion: a shunt S = Ig G / (I minus Ig) makes an ammeter. A series resistance R = V / Ig minus G makes a voltmeter. Example: G = 50 ohm, Ig = 1 mA. For a 1 A ammeter, S is about 0.05 ohm. For a 10 V voltmeter, R = 9,950 ohm.
Read the whole passage first. Underline the data. Most sub-questions can be answered from the passage plus one formula.

Section E: Five-Mark Long Answers (15 Marks)

#	Expected question	Evidence
19	A derivation from Electrostatics, such as the field of a dipole or the energy stored in a capacitor	2026 paper (Electrostatics derivations)
20	A derivation from Ray Optics, such as the lens maker's formula or refraction at a spherical surface	2026 paper (Ray Optics derivations)
21	A derivation from EMI, such as motional emf or a transformer	2026 paper (EMI and AC derivations)
22	A derivation from AC, such as the impedance of a series LCR circuit or the condition for resonance	2026 paper (EMI and AC derivations)

Coverage names the chapters. The specific derivations above are my suggestions of the standard ones in each chapter, so learn the full list. Our derivation list with step-wise marking covers them.

Answer format

Step	What to do
1	Draw the labelled diagram first. It earns a mark in most derivations
2	State the assumptions and the law you begin from
3	Show every algebra step. Do not jump
4	Box the final expression
5	Write units in numerical sub-parts

One teacher noted that sign errors and overlooked requirements can cost high scorers marks.

#	Expected question	Evidence
23	Current electricity: Kirchhoff's rules, a potentiometer comparison, or a cell with internal resistance	Syllabus. Not named in the 2026 coverage I could read
24	Magnetism: force on a moving charge, a cyclotron or a solenoid. The Magnetic Effects block is 17 marks	Syllabus, per EdexLive's unit marks
25	Atoms: Bohr model, energy levels and spectral series	Syllabus. Not named in the 2026 coverage I could read

4-Week Practice Plan

Week	Focus	Questions in this list
Week 1	Electrostatics and Current Electricity	8, 10, 13, 19, 23. Do one derivation a day
Week 2	Magnetism, EMI and AC	4, 21, 22, 24. Practise the torque numericals
Week 3	Optics and Modern Physics	7, 12, 15, 18, 20, 25, 5, 6, 17. Redraw every ray diagram
Week 4	Semiconductors, case studies and full papers	11, 14, 16, then two full timed papers

This is a suggestion, not an official schedule. Our numericals guide covers the shortcuts, and our case-study practice has more passages.

Paper-Day Time Plan

The 2026 paper was long, and some students said three hours was not enough to revise. Plan for speed.

Section	Suggested time	Note
A (16 MCQs)	About 25 minutes	Skip long calculations and return
B (5 questions)	About 15 minutes	Write the formula and the unit
C (7 questions)	About 50 minutes	Multi-step numericals need care
D (2 case studies)	About 20 minutes	Read the passage once, carefully
E (3 derivations)	About 45 minutes	Diagram first
Review	About 15 minutes	Check signs and units

These timings are illustrative. CBSE does not publish a per-section time split.

Frequently Asked Questions

Are these the exact questions in the 2027 Physics board exam?

No. Nobody outside CBSE knows the 2027 questions. This list ranks question types by evidence from the paper design, what teachers reported about the 2026 paper, and the syllabus. Any page or channel that promises the actual paper is a scam.

What is the paper design for CBSE Class 12 Physics 2027?

The 2026-27 sample paper has 33 compulsory questions for 70 marks in 3 hours: 16 one-mark questions, five 2-mark, seven 3-mark, two 4-mark case studies and three 5-mark long answers. Practical and internal assessment carry the other 30 marks.

Was the 2026 Physics paper difficult?

Reports differ. Teachers quoted by NDTV and Times Now called it easy to moderate, though lengthy. Other teachers called it moderate to difficult. The common points were many derivations, multi-step numericals and a long paper that left some students no time to revise.

Which Physics units carry the most marks?

I confirmed three units: Electrostatics at 16 marks, the Magnetic Effects of Current and Magnetism block at 17 marks, and Electronic Devices at 7 marks. Check the CBSE syllabus PDF for the rest.

How many derivations should I learn?

All the standard ones. In 2026, Section E drew derivations from Electrostatics, Ray Optics, and EMI and AC, and many questions were similar to previous year questions. One teacher noted that each section carried derivations. See our derivation list for the standard set.

Is Physics paper easier for JEE aspirants?

One Gurugram teacher quoted by Times Now said JEE aspirants looked confident because the paper matched their preparation. A Noida teacher said the paper did not seem designed around Biology students, and that students with strong mathematical understanding may find it easier.
