Problem

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 : (1)

\frac{1}{2}CV_0^2

(2)

\frac{1}{3}CV_0^2

(3)

\frac{1}{4}CV_0^2

(4)

\frac{1}{6}CV_0^2
