In the circuit shown below, what will be the reading of the voltmeter $V_3$ and ammeter A?

Voltage across L and C cancel out.

So, voltmeter reading across R is ${\mathrm{V}}_{\mathrm{rms}}=220\mathrm{V}$

The ammeter reading is ${\mathrm{I}}_{\mathrm{rms}}=\frac{{\mathrm{V}}_{\mathrm{rms}}}{\mathrm{R}}=\frac{220}{100}=2.2\mathrm{A}$
