In the given series LCR circuit, the voltmeter and ammeter readings are
V = 100 V ;i = 2 A
⇒ XL=XC ⇒ The L – C – R circuit is in resonance condition.
∴ The series L – C – R circuit behaves like a pure resistor circuit, where the potential drop across resistor is equal to the applied ac voltage.
And current through the circuit =i0=VRR=10050=2A
