Alternating Current

Question:

In series LCR circuit, the rms potential drop across R. L and C are V, 2 V and 2 V volts respectively. The source voltage is:

Options:

V

2 V

3 V

5 V

Correct Answer:

V

Explanation:

The correct answer is Option (1) → V

The total source voltage ($V_{source}$) is -

$V_{source}=\sqrt{{V_R}^2+(V_L-V_C)^2}$

$=\sqrt{V^2-(V-V)^2}$

$=V$
