When a voltage source, v, is connected to the capacitor, the source deposits a positive charge, q, on one plate and a negative charge, –q, on the other as in Fig. 4.23. Capacitance, C, is the ratio of the charge q on one plate of a capacitor to the voltage difference v between the two plates.

RC Circuits. An (RC) circuit is one containing a resisto r (R) and capacitor (C). The capacitor is an electrical component that stores electric charge. Figure shows a simple (RC) circuit that employs a DC (direct current) voltage source. The capacitor is initially uncharged. As soon as the switch is closed, current flows to and from …
Capacitors in Parallel Figure 19.20(a) shows a parallel connection of three capacitors with a voltage applied.Here the total capacitance is easier to find than in the series case. To find the equivalent total capacitance C p C p, we first note that the voltage across each capacitor is V V, the same as that of the source, since they are connected directly to it …

The capacitance of a capacitor tells you how much charge is required to get a voltage of 1V across the capacitor. Putting a charge of 1uC into a capacitor of 1uF will result in a voltage of 1V across its terminals. An ideal capacitor can take an infinite amount of charge resulting in an infinitely high voltage.
