Alternating Current — NEET/JEE Questions, Notes & Weightage
Class 12 Electromagnetism NEET weightage: High 218 questions
Covers AC circuits with resistors/inductors/capacitors, impedance, resonance in LCR circuits, and power in AC circuits. LCR-circuit impedance and resonance-frequency numericals are this chapter's most reliable, formula-driven contribution.

Frequently asked questions
What numerical is asked most?
Finding the impedance, current, or resonant frequency of a series LCR circuit given resistance, inductance, and capacitance is the chapter's most frequently repeated question type.
Is power in AC circuits (power factor) tested?
Yes — calculating average power using the power factor (cos φ) is a standard, recurring numerical, especially in JEE.
