Part 1 of Class 12 Physics covers electrostatics, current electricity, magnetic effects of current and magnetism, electromagnetic induction and alternating current, and electromagnetic waves. These are arguably the highest-weightage topics in JEE Physics, with nearly 40% of questions drawn from this volume alone.

The book excels at building intuition around electric fields, potential, circuits, and magnetic interactions — all of which are core to JEE problem-solving. Work through the derivations on your own, especially Gauss's law applications and AC circuit analysis. After finishing the NCERT exercises, move to DC Pandey or Irodov for the depth JEE Advanced demands. The conceptual clarity you gain from this part will directly determine your Physics score.
