Importance of a Bypass Capacitor in a Circuit | ETcourse

The purpose of the bypass capacitor is to increase the AC voltage gain of the circuit. However, the DC voltage drop across R E is necessary for biasing, but any AC signal that is dropped across R E represents a direct loss in AC output voltage. Emitter Resistor (R E) is required to increase the DC stability of the circuit during DC analysis …

In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.

Capacitor and Capacitance Simplified & Explained

The capacitance is only a function of the physical dimensions (geometry) of the conductors and the permittivity of the dielectric material used in a capacitor. There are three basic factors of capacitor construction determining the amount of capacitance created i.e plate area, plates spacing and dielectric material used.
