Q.

An inductor of 0.5 mH, a capacitor of 20 μF and a resistance of 20 Ω are connected in series with a 220 V AC source. If the current is in phase with the emf, the amplitude of current of the circuit is xA. The value of x is _______.            [2023]


Ans.

(242)

XL=XC

So, Z=R=20 Ω

irms=22020=11

imax=112=242
