Ohm's law, Kirchhoff's rules and the Wheatstone bridge are NCERT favourites with a high marks-per-hour ratio.
Physics Part 1 (Class 12) — Chapter 3: Current Electricity, Pages 83–115
Key pages to master: 85, 93, 100, 107, 112
Series adds R; parallel adds 1/R
KCL at junctions, KVL around loops; assign current directions and stick to them
Balanced when P/Q = R/S — no current through galvanometer
P = I²R = V²/R; convert between all three forms
Practise Kirchhoff loops on 5 circuits and the balanced Wheatstone condition P/Q = R/S.
On average, 3 questions per paper come from Current Electricity — about 100% of the Physics paper, worth roughly 15 marks.
It is rated Medium. Practise Kirchhoff loops on 5 circuits and the balanced Wheatstone condition P/Q = R/S.
