The Capacitance of a Capacitor. Capacitance is the electrical property of a capacitor and is the measure of a capacitors ability to store an electrical charge onto its two plates with the unit of capacitance being the Farad (abbreviated to F) named after the British physicist Michael Faraday. Capacitance is defined as being that a capacitor has ...

which is plotted in Fig. 8.For the given form of excitation, the efficiency is again independent of both T and the voltage amplitude. The efficiency is zero for q = 0, which corresponds to a purely resistive element. The efficiency is only 0.25 for q = 1, as energy is lost at the instant when the voltage across the ideal capacitive element switches.
A simple circuit contains the minimum amount of components that allow it to be a functional electric circuit: a voltage source ε (battery), a resistor R, and a loop of wires for current I to flow around (see Figure 6 below). We usually ignore any resistance from the wires. Figure 6. Simple circuit diagram.
Round-trip efficiency is the ratio of energy charged to the battery to the energy discharged from the battery and is measured as a percentage.
