Question

In the given circuit the readings of voltmeter $V_1$ and $V_2$ are 300 volts each. The readings of the voltmeter $V_3$, and ammeter A are respectively

• A. 150V, 2.2A
• B. 220V, 2.2A
• C. 220V, 2.0A
• D. 100V, 2.0A

Answer 1

The correct option is B

220V, 2.2A

$V_1=V_2$

$\Rightarrow {\text{IX}}_{\text{L}}={\text{IX}}_{\text{C}}\Rightarrow {\text{X}}_{\text{L}}={\text{X}}_{\text{C}}$

The circuit is in resonance

$\therefore \text{V}={\text{V}}_3=220\text{V}$

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