IEVref: 131-12-13 ID: Language: en Status: Standard Term: capacitance Synonym1: Synonym2: Synonym3: Symbol: C Definition: for a capacitive two-terminal element with terminals A and B, quotient of the electric charge q at A by the voltage (131-11-56) uAB between the terminals $C=\frac{q}{{u}_{\mathrm{AB}}}$ where the sign of the electric charge is determined by taking the electric current in the time integral defining this charge as positive if its direction is from A to B and negative if its direction is from B to ANote 1 to entry: A capacitance cannot be negative. Note 2 to entry: The coherent SI unit of capacitance is farad, F.
