Question

Two capacitors of capacitance 3 f3 f and 6 f6 f are charged to a potential of 12 v each. They are now connected to each other, with the positive plate of one to the negative plate of the other. Then

Answer 1

When a steady state is reached and the current goes to zero, the voltage on the two capacitors must be equal since they are connected together. Since they both have the same capacitance the charge will be divided equally between the capacitors so each capacitor will have a charge of and a voltage of .
