Definition: | for a capacitive two-terminal element with terminals A and B, derivative of the electric charge q with respect to the voltage u_{AB} (131-11-56) between the terminals:
where the sign of the electric charge is determined by taking the current in the time integral defining the electric charge as positive if its direction is from A to B and negative in the opposite case NOTE – For an ideal capacitor, the differential capacitance | ||
