Question

The readings of ammeter and voltmeter in the given circuit are respectively (A) 2.2 A , 220 V (B) 2 A , 200 V (C) 2.5 A , 200 V (D) 2 A , 220 V

Since, the voltage across inductor and capacitor is same, so they are in resonance i.e.,

X_{L} = X_{C}

The impedance of circuit,

Z = R^{2} + (X_{L} - X_{C})^{2} = R

∴

Voltage across,

R = 220 V

By Ohm's law,

V = I R

\Rightarrow I = \frac{V}{R} = \frac{220}{100} = 2.2 A

Hence, ammeter reading is

2.2 A

and voltmeter reading is

220 V

.
