Alternating CurrentMedium

Question

In the series LCR circuit as shown in figure, the voltmeter and ammeter readings are :
                                    

Options

A.V = 100 volt, I = 2 amp
B.V = 100 volt, I = 5 amp
C.V = 1000 volt, I = 2 amp   
D.V = 300 volt, I = 1 amp

Solution

At resonance (VC = VL)
                   V = Irms × R
= × R        (here z = R)
V = Vrms = 100 volt    &    Irms = = 2 Amp.
