Question

A condenser of a capacity of $500\mu F$ is charged at the rate of $50\mu C/s$. The time taken for charging the condenser to $10V$ will be :
( Assume initial charge on condenser was zero.)

• A. 10 s
• B. 25 s
• C. 50 s
• D. 100 s

Answer 1

The correct option is D 100 s

The maximum charge for 10 V is $Q=500\times 10=5000\mu F$
As charge rate $50\mu C/s$ , so required time for charging is ,
$t=\frac{5000}{50}=100$ s
