# Capacitor problem

**1. The problem statement, all variables and given/known data**

A [itex]5.0[/itex][itex]\mu[/itex][itex]F[/itex] capacitor is charged to [itex]12 V[/itex] . The positive plate of this capacitor is now connected to the negative terminal of a [itex]12 V[/itex] battery and vice versa. Calculate the heat developed in the connecting wires.

**2. Relevant equations**

[itex]W = QV[/itex]

[itex]E = 0.5CV^2[/itex]

**3. The attempt at a solution**

I know from the above 2 equations that half of the energy supplied by the battery should be lost as heat . But I don’t know how to proceed with this problem ?
