A capacitor of capacitance `C` which is initially charged up to a potential differnce `epsilon` is connected with a battery of emf `epsilon` such that the positive terminal of the battery is connected with the positive plate of the capacitor. Find the heat loss in the circuit the process of charging.

Explanation

Since the initial and final charge on the capacitor is same before and after connection.
Here no charge will flow in the circuit so heat loss = 0
