Electrostatics

Highest-weightage unit in the paper. Gauss's law and capacitors do the heavy lifting.

NMC Unit 11
Ch1

Electric Charges and Fields

Coulomb's law and superpositionElectric field and field linesElectric dipole and dipole fieldElectric fluxGauss's law and its applications
≈ 2 Q
Ch2

Electrostatic Potential and Capacitance

Potential and equipotential surfacesPotential energy of charges and dipolesConductors and electrostatic shieldingCapacitor combinationsDielectrics and polarisationEnergy stored in a capacitor
≈ 2 Q
12

Current Electricity

Circuit-reduction speed matters more than theory here. Kirchhoff every day.

NMC Unit 12
Ch3

Current Electricity

Drift velocity and resistivityOhm's law and V–I characteristicsSeries and parallel combinationsEMF and internal resistanceKirchhoff's rulesWheatstone bridgeTemperature dependence of resistance
≈ 2 Q
13

Magnetic Effects of Current and Magnetism

Two chapters, very unequal weight. Chapter 4 is where the questions live.

NMC Unit 13
Ch4

Moving Charges and Magnetism

Biot–Savart lawAmpere's circuital lawLorentz forceForce between parallel currentsTorque on a current loopMoving coil galvanometer and its conversion
≈ 2 Q
Ch5

Magnetism and Matter

Current loop as a magnetic dipoleBar magnet and solenoid analogyTorque and potential energy of a dipoleMagnetisation and magnetic intensityPara-, dia- and ferromagnetism
≈ 1 Q
14

Electromagnetic Induction and Alternating Currents

Phasors and resonance. Lenz's law sign questions are a standing favourite.

NMC Unit 14
Ch6

Electromagnetic Induction

Faraday's lawsLenz's law and conservation of energyMotional EMFEddy currentsSelf and mutual inductanceEnergy stored in an inductor
≈ 1–2 Q
Ch7

Alternating Current

RMS and peak valuesAC through R, L and CPhasor diagramsSeries LCR circuit and resonancePower factor and wattless currentTransformer
≈ 2 Q
15

Electromagnetic Waves

Smallest unit on the paper and the cheapest full mark available. Learn the spectrum order.

NMC Unit 15
Ch8

Electromagnetic Waves

Displacement currentNature and properties of EM wavesTransverse character and energy transportElectromagnetic spectrum and uses
≈ 1 Q
16

Optics

The largest single unit in Physics. Ray optics is formula work, wave optics is reasoning.

NMC Unit 16
Ch9

Ray Optics and Optical Instruments

Reflection at spherical mirrorsRefraction and total internal reflectionLens maker's formulaCombination of lenses and powerPrism, deviation and dispersionCompound microscope and telescopes
≈ 2–3 Q
Ch10

Wave Optics

Huygens' principleYoung's double-slit experimentConditions for interference and fringe widthSingle-slit diffractionPolarisation and Brewster's law
≈ 2 Q
17

Dual Nature of Matter and Radiation

Short, graph-based and reliably asked. Stopping potential graphs repay practice.

NMC Unit 17
Ch11

Dual Nature of Radiation and Matter

Photoelectric effectEinstein's photoelectric equationWork function and stopping potentialParticle nature of lightde Broglie wavelength
≈ 2 Q
18

Atoms and Nuclei

Modern physics scores well for the time invested. Binding-energy curve logic is key.

NMC Unit 18
Ch12

Atoms

Alpha-particle scatteringRutherford's nuclear modelBohr model and postulatesEnergy levelsHydrogen spectral series
≈ 1–2 Q
Ch13

Nuclei

Nuclear size and densityMass defect and binding energyBinding energy per nucleon curveNuclear fission and fusionRadioactive decay law and half-life
≈ 2 Q
19

Electronic Devices

Rationalisation cut the transistor out. What remains is diodes, and it is compact.

NMC Unit 19
Ch14

Semiconductor Electronics

Intrinsic and extrinsic semiconductorsp-n junction and depletion layerForward and reverse bias characteristicsDiode as a rectifierZener diode as a voltage regulatorLED, photodiode and solar cell
≈ 2–3 Q
20

Experimental Skills

No NCERT chapter behind it — it comes from the Class 11 and 12 practical lists.

NMC Unit 20
Ch—

Experimental Skills

Vernier callipers and screw gaugeMetre bridge and Ohm's lawFocal length of mirrors and lensesRefractive index of a prismDiode I–V characteristicsLeast count and error handling
≈ 1 Q

Not in the NEET syllabus

Cut by the NCERT rationalisation or trimmed by the NMC. Several are mid-chapter topics rather than whole chapters, so check before revising an old note set.
