Question

The readings of the ammeter and voltmeter in the given circuit are respectively.

 

पर्याय

• 2.2 A, 220 V

• 2 A, 200 V

• 2.5 A, 200 V

• 2 A, 220 V

Answer 1

2.2 A, 220 V

Explanation:

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

The impedance of the circuit,

Z = `sqrt(R^2 + (X_L - X_C)^2)` = R

∴ Voltage across, R = 220 V

By Ohm's law, V = IR

⇒ l = `V/R = 220/100` = 2.2 A

Hence, the ammeter reading is 2.2 A and the voltmeter reading is 220 V.
