The capacitor was originally known as a condenser or condensator but is not widely used nowadays. Capacitance of a Capacitor
10.4: Reactance and Impedance
Recall that the voltage across a capacitor cannot change instantaneously, (i = C, dv/dt). For an inductor, the voltage leads the current by 90 degrees. Similarly, the current through an inductor cannot change instantaneously due to (v = L, di/dt). While ideal capacitors and inductors do not exhibit resistance, the voltage does react to ...
