Q. In the given circuit the reading of voltmeter $V_{1}$ and $V_{2}$ are $300$ volts each. The reading of the voltmeter $V_{3}$ and ammeter $A$ are respectively

150 V, 2.2 A

220 V, 2.2 A

220V,2.0A

100V,2.0A

As $V_{L} = V_{c} = 300 V$ , therefore the given series LCR circuit is in resonance.
$∴ V_{R} = V = 220 V$
$Z = R = 100 Ω$
Current, $I = \frac{V}{Z} = \frac{220 V}{100 Ω} = 2.2 A$
Hence, the reading of the voltmeter $V_{3}$ is $220 V$ and the reading of ammeter $A$ is $2.2 A$ .
