The rms voltage measured across each of the circuit elements in figure is as shown when the circuit is excited by a sinusoidal voltage sources. The rms value of the source voltage is—
-
- 21 V
- 4 V
- 5 V
- 1 V
Correct Option: C
We know that the net voltage in RLC circuit is given as
Erms = (VR)2 + (XL – XC)2
= (3)sup>2 + (14 – 10)sup>2
= 9 + 16
= 5 V
