Al-Huda Science Academy has designed Class 12 MCQs Physics Chapter 16 Alternating Current for board, MdCat and ECAT preparation. These MCQs help students to prepare for their entry test papers.
Chapter 16 Alternating Current includes topics:
- Alternating current
- Peak to Peak value
- Phase lag and Phase lead
- AC through capacitor
- AC through inductor
- Impedance
- Power in AC circuit
- Parallel resonance circuit
- Series resonance circuit
- Electromagnetic waves
