Question -

A 60 μF capacitor is connected toa 110 V, 60 Hz ac supply. Determine the rms value of the current in thecircuit.



Answer -

Capacitance of capacitor, C =60 μF = 60 × 10−6 F

Supply voltage, =110 V

Frequency, ν =60 Hz

Angularfrequency, ω
Capacitive reactance 

Rms value of current is given as:

Hence, the rms value of currentis 2.49 A.
