Question

Calculate the value admittance (Y) of the RLC

parallel circuit connected across 240volts/50Hz AC

supply and 8 Amp. Current is passed through it ? |​

Answer 1

Explanation:

The frequency of AC source =f=50Hz

Thus the impedance of the inductor, X

L

=ωL=(2πf)L=20πΩ

Resistance of the resistor =20Ω

Thus, the net impedance of the circuit =

X

L

=65.94Ω

Thus, the current in the circuit =
