Question

In the given series LCR circuit, the reading of the hot wire voltmeter $\left(V\right)$ across resistor will be -

• A. $600\text{V}$
• B. $900\text{V}$
• C. $200\text{V}$
• D. $400\text{V}$

Answer 1

The correct option is C $200\text{V}$


According to the given circuit diagram, $V_L=V_C$.

Hence, the circuit resonates.

At resonance,

$V_R=E$

So, the reading of the hot wire voltmeter will be equal to $200\text{V}$.

Hence, option $\left(C\right)$ is the correct answer.
