Question

In the given circuit the reading of voltmeter V1 and V2 are 300 volts each. The reading of the voltmeter V3 and ammeter A are respectively
           

Options

A.150 V, 2.2 A
B.220 V, 2.2 A
C.220 V, 2.0 A
D.100 V, 2.0 A

Solution

        
As 300 VL = VC = 300V, therefore the given series LCR circuit is in resonance.
∴ VR = Vc = 220 V
Z = R = 100Ω
Current, I = = 2.2 A
Hence, the reading of voltmeter V3 is 220 V and the reading of ammeter A is 2.2 A.
