Question

In a series LCR circuit the rms voltages across the inductance, capacitance and resistance are respectively 4 V , 8 V and 5 V . The RMS voltage of the AC source in the circuit is, 17 V, 13 V, 5 V, 6.4 V

MARKS App · Accepted Answer

Given V L = 4 V , V C = 8 V , V R = 5 V Using V = V R 2 + V C ~ V L 2 = 5 2 + 8 - 4 2 = 41 = 6.4 V
