Question

Find the charge on capacitor $C_{3}$

Given, that $C_{1}=C_{2}=C$ and $C_{3}=C_{4}=3 C$.

• A. $\frac{3}{2} C V$
• B. $\frac{ CV }{2}$
• C. $3 \,C \,V$
• D. $2 \,C\, V$

Answer 1

Answer: (A)

$C_{\text {net }}=2 C$
$q=2 C V$
$\frac{q_{1}}{q_{2}}=\frac{1}{3}$
$3 q_{1}=q_{2}$
$q_{1}+q_{2}=2 C V$
$q_{1}=\frac{C V}{2}$
$q_{2}=\frac{3 C V}{2}$
