Q118 / 180 · AIIMS 2012 · Physics

Find the voltage drop across a capacitor connected with a resistance and a battery of $60 \mathrm{~V}$ in series after a long time.

A
$0 \mathrm{~V}$
Correct answer
B
$60 \mathrm{~V}$
C
$30 \mathrm{~V}$
D
$38 \mathrm{~V}$

Solution

After a long time the capacitor has become fully charged, the entire battery voltage $60 \mathrm{~V}$ appears across the capacitor.

Hence, the correct answer is option: 'B'.
