In an AC circuit capacitive reactance of capacitor is X_C=50 2 and inductive reactance of inductor is X_L=50 2 ohm . If the source voltage is 100 volts. Then find the current passing through the source.

Correct answer

0

Step-by-step solution

I_L= 100 50 2 = 2 ~A I_C= 100 50 2 = 2 I_ source = I _ L - I _ C =0
