Question

The charge on 3$\mu F$ capacitor shown in the figure is

• A. 2 $\mu C$
• B. 10 $\mu C$
• C. 6 $\mu C$
• D. 8 $\mu C$

Answer 1

The correct option is B 10 $\mu C$

Since all the capacitors are connected in series,
$\therefore$ equivalent capacitance is
$\frac{1}{C_{eq}}=\frac{1}{2}+\frac{1}{3}+\frac{1}{6}=1\therefore C_{eq}=1\mu F$
Charge on each capacitor is same
$q=C_{eq}V=1\times 10=10\mu C$ ($\because V=10V$)
