Question

In the figure a capacitor of capacitance $2\mu F$ is connected to a cell of electromotive force $20$ volt. The charge on the capacitor is:

• A. $40\mu F$
• B. $20\mu F$
• C. $10\mu F$
• D. $22\mu F$

Answer 1

The correct option is A $40\mu F$

We know that,

$Q=CV$

$=2\times 20$

$=40\mu F$

Hence, Option $A$ is correct.
