In both digital and analog electronic circuits a capacitor is a fundamental element. It enables the filtering of signals and it provides a fundamental memory element. The capacitor is an element that stores energy in an electric field. The circuit symbol and associated electrical variables for the capacitor is shown on Figure 1. Figure 1.
An electric circuit element that has an ability of storing electrical energy in the form of electric field is called a capacitor. The property of the capacitor by virtue of which it store electrical energy is known as capacitance.
Alter, the current in a capacitor is equal to capacitance C times the rate of change of voltage. Hence, this is known as the definition of the capacitor. Since the active elements should be able to provide power or power gain to the circuit for an infinite duration of time. That is why the charged inductor and capacitor are not ACTIVE elements.
The circuit containing only a pure capacitor of capacitance C farads is known as a Pure Capacitor Circuit. The capacitors stores electrical power in the electric field, their effect is known as the capacitance. It is also called the condenser. The capacitor consists of two conductive plates which are separated by the dielectric medium.
An a.c. circuit, when contains only a capacitor or a condenser, has capacitance only. Such a circuit is shown in fig 31 (a). As inductance causes a voltage drop across it and an angle of phase difference between applied voltage and the circuit current, so does the capacitance.
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.
