Q1:

The rms voltage measured across each of the circuit element in figure is as shown, when the circuit is excited by a sinusoidal voltage Es, the rms value of the source voltage es is

A 10 volt

B 2 volt

C Es

D 5 volt

ANS:D - 5 volt

Voltage across C = -10jv Voltage across L = + 14 jv source voltage Es = VR + jVL - jVC = 3 + j. 14 - j. 10 3 + j4 rms of Es = VR2(VL - VC)2 = 32 + 42 5 volt.
