Question

In an A.C. circuit, a capacitor of 10 $\mu$F is connected with source of 240 volts and 60Hz. The effective value of current in ampere will be_______

• A. 1.9
• B. 0.28
• C. 0.9
• D. 0.14

Answer 1

The correct option is C 0.9

$i=\frac{V}{X_C}$

$=\frac{V}{\frac{1}{wC}}$
$=V2\pi fC$

$=240\times 2\pi \times 60\times 10\times {10}^{-6}$

$=0.9A.$
