Find the rms current in a capacitor of 0.1 μF, when an AC voltage of 5 V and frequency of 5 kHz is applied to it.

Find the rms current in a capacitor of 0.1 μF, when an AC voltage of 5 V and frequency of 5 kHz is applied to it. Correct Answer 15.71 mA

Rms current in capacitor is given by,

Irms = V ω C

Where V = voltage across capacitor

C = 0.1 μf

f = 5 kHz

ω = 2 π f

now Irms = 5× 2× π × 5 × 103 × 0.1 × 10-6 = 15.71 mA
