Suppose that we have two 100-μF capacitors. One is charged to an initial voltage of 50 V, and the other is charged to 100 V. If they are placed in series with the positive terminal of the first connected to the negative terminal of the second, determine the equivalent capacitance and its initial voltage. Now compute the total energy stored in the two capacitors. Compute the energy stored in the equivalent capacitance. Why is it less than the total energy stored in the original capacitors?

Suppose that we have two 100-μF capacitors. One is charged to an initial voltage of 50
V, and the other is charged to 100 V. If they are placed in series with the positive terminal of the
first connected to the negative terminal of the second, determine the equivalent capacitance and
its initial voltage. Now compute the total energy stored in the two capacitors. Compute the
energy stored in the equivalent capacitance. Why is it less than the total energy stored in the
original capacitors?
