Question

Two capacitors 3 u F and 6 u F are connected in series with 30 V cell. After getting charged, the cell is removed, positive plates of the capacitors are connected together with a wire and negative plates of the capacitors are connected together with another wire. Find their equivalent capacitance and loss of energy in this process.

Answer 1

Answer:

equivalent capacitance = 2uF

loss of energy 900uJ
