Question

Find the charge stored in $3\mu F$ capacitors :

• A. $30\mu C$
• B. $40\mu C$
• C. $50\mu C$
• D. $60\mu C$

Answer 1

The correct option is A $30\mu C$

Here all the capacitors are connected in parallel so the potential across them is same i.e $V=10V$

Using $Q=CV$, the charge stored in $1\mu F$ is $Q_1=1\times 10=10\mu C$, charge stored in $2\mu F$ is $Q_2=1\times 10=20\mu C$ and charge stored in $3\mu F$ is $Q_3=3\times 10=30\mu C$
