Alternating Current

Question:

At any instant t the values of voltage applied and the current through a series LCR circuit are given as:

$V=\frac{1}{\sqrt{2}} \sin (100 \pi t) V$

$I=\frac{1}{\sqrt{2}} \sin (100 \pi t+\frac{\pi}{3}) A$

The average power consumed in the circuit is given by:

Options:

$\frac{1}{8} W$

$\frac{1}{4} W$

$\frac{1}{2} W$

$\frac{\sqrt{3}}{4} W$

Correct Answer:

$\frac{1}{8} W$

Explanation:

The correct answer is Option (1) → $\frac{1}{8} W$
