Capacitance represents the efficiency of charge storage and it is measured in units of Farads (F). The presence of time in the characteristic equation of the capacitor introduces new and exciting behavior of the circuits that contain them. Note that for DC (constant in time) dv signals ( = 0 ) the capacitor acts as an open circuit (i=0).
Hence, when capacitor is connected in AC circuits and the applied voltage is changing continuously with time the charging current is passed through the capacitor. Therefore another important property of capacitor is “capacitor passes the AC supply”. Figure bellow shows the capacitor circuit in which the capacitor is connected with the AC source.
From this working of the capacitor it seems that, the capacitance of the capacitor in the AC circuit depends upon the operating frequency of the AC source. Hence, when capacitor is connected in AC circuits and the applied voltage is changing continuously with time the charging current is passed through the capacitor.
It is a function of the geometric characteristics of the capacitor - plate separation (d) and plate area (A) - and by the permittivity (ε) of the dielectric material between the plates. Capacitance represents the efficiency of charge storage and it is measured in units of Farads (F).
We use the denition of capacitance, C= Q=V and consider the circuit to be a single capacitor in a black box with two wires sticking out left and right. The voltage applied is that supplied by the power source, namely V. The charge that goes into the box through the wire on the left is the sum of the charges that go onto capacitors 1 and 2.
If we only have DC sources in the circuit, at steady state capacitors act like open circuit and inductors act like a short circuit. In the following circuit find the energy that is stored in the inductor and capacitor, when the circuit reaches steady state.
