Question

1. A 100 uC capacitor is connected across 220 V, 50 Hz power supply. What is the displacement current through the capacitor? a) 3A b) 5A c) 7A d) 9A​

Answer 1

Answer:

Answer

Correct option is

B

0.6

2

A

RMS value of applied voltage = 200 V

Impedance of a capacitor is given by:

X

C

=

2πfC

1

Hence, rms current through it is:

I=

X

C

V

I=200×2×π×50×10×10

−6

I=0.2π A

Peak current, I

max

=

2

I

=0.628
