Question

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

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

Answer 1

Answer: (C)

200 V

Answer 2

: Here, $V_{L} = V_{C} = 100V,V = 200V$

As $V = \sqrt{V_{R}^{2} + (V_{L} - V_{C})^{2}}$

$\therefore 200 = \sqrt{V_{R}^{2} + (100 - 100)^{2}} = V_{R}$

or ,$V_{R} = 200V$
