Question

In the circuit shown below, what will be the readings of the voltmeter and ammeter

A

800 V, 2A

B

300 V, 2A

C

220 V, 2.2 A

D

100 V, 2A

Answer

220 V, 2.2 A

Explanation

Solution

V_L = V_C; This is the condition of resonance and in resonance V = V_R = 220 V.

In the condition of resonance current through the circuit $i = \frac{V_{rms}}{R} = \frac{220}{100} = 2.2A.$
