Two identical capacitors (capacitance = C) are connected in parallel and the combination is connected in series to a third identical capacitor. The equivalent capacitance of this arrangement is:
The diagram shows six, 6F capacitors. The capacitance between points a and b is:
A 20-F capacitor is charged to 200 V. Its stored energy is:
A 2F and a 1F capacitor are connected in series and charged by a battery. They store energies P and Q respectively. When disconnected and charged separately using the same battery, they have energies R and S respectively. Then:
