Question

A capacitor $C$ is fully charged with voltage $V_0$. After disconnecting the voltage source, it is connected in parallel with another uncharged capacitor of capacitance $\frac{C}{2}$. The energy loss in the process after the charge is distributed between the two capacitors is

Select the correct option:

$\frac{1}{4} C V_0^2$

$\frac{1}{3} C V_0^2$

$\frac{1}{6} C V_0^2$

$\frac{1}{2} C V_0^2$

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

Solution

$\Delta U=\frac{1}{2} \frac{C_1 C_2}{C_1+C_2} V_0^2=\frac{1}{6} C V_0^2$
