An alternating voltage of 220 V, 50 Hz frequency is applied across a capacitor

An alternating voltage of 220 V, 50 Hz frequency is applied across a capacitor of capacitance 2 μF. The impedence of the circuit is

Options

(a) π/5000
(b) 1000/π
(c) 500π
(d) 5000/π

Correct Answer:

5000/π

Explanation:

Impedance of a capacitor is Xc = 1 / ωC

Xc = 1 / 2πfC = 1 / (2π × 50 × 2 × 10⁻⁶) = 5000 / π
