Question

In the circuit shown in figure, what will be the reading of the voltmeter?

• A. $300V$
• B. $900V$
• C. $200V$
• D. $400V$

Answer 1

Answer: (C)

Here, $V_L=V_C=100V$, $V=200V$
As $V=\sqrt{V_R^2+{\left(V_L-V_C\right)}^2}$
$\therefore 200=\sqrt{V_R^2+{\left(100-100\right)}^2}$
$=V_R$ or $V_R=200V$
