Question

In a LCR series circuit, the potential difference between the terminals of the inductance is 60 V, between the terminals of the capacitor is 30 V and that across the resistance is 40 V. Then, supply voltage will be equal to

Accepted Answer

Correct answer: A. (a) In LCR series circuit, V= V_R^2+(V_L-V_C)^2= (40 )^2+ (60-30 )^2 = (40 )^2+ (30 )^2= 1600+900=50 V
