Zero, because V^l and Vc nulify each other and effectively the circuit is resistive in nature. Class 12 Physics Chapter 7 Alternating current Session 2024-2025.
Capacitive reactance of a capacitor is the opposition offered by it for flow of a current through it. Capacitive reactance Xc = 1/Cw , where w is the angular frequency of current supply. SI unit of capacitive reactance is ohm ...
Here Xc = 100Ω, v = 5/π kHz = 5000/π Hz ∴ C = 1/Xc . 2πv = 1/100 × 2π × 5000/π = 10-⁶F = 1µF. Class 12 Physics Chapter 7 Alternating current Session 2024-2025.
(i) In an inductor current logs behaind the voltage by a phase angle of π/2 . (ii) In a capacitor current leads the voltage by a phase angle of π/2 . Class 12 Physics Chapter 7 Alternating current Session ...
