Capacitance definition

Capacitance is the ratio of the electric charge stored on a conductor or capacitor to the voltage across it. It is used to size capacitors and to relate charge and voltage in electric circuits.

C=\frac{Q}{V}

What the symbols mean

capacitance (farads, F)
electric charge stored (coulombs, C)
voltage across the capacitor (volts, V)
