Uses of Capacitors at a glance

The mechanical process of storing charges in a conductor is called capacitor or, the mechanical process by which electricity is stored is called capacitor. A capacitor is formed by two conductors separated by a small distance. They are used in virtually every area of electronics, and they perform a variety of different tasks. Although capacitors operate in the same way whatever the capacitor application or use, there are several different uses for capacitors in circuits.

  • Capacitors are used for tuning in telegraph, telephone and radio receivers.
  • Capacitors are used for controlling the speed of electric fans.
  • Capacitors are used for coupling in amplifiers.
  • It is used for charging and discharging in an electric circuit.
  • It is used for d.c. blocking in an electric circuit.
  • Capacitors are used in filter circuits.
  • Capacitors are used in oscillators.
  • Capacitors are used as sensors to measure a variety of things, including air humidity, fuel levels, and mechanical strain.
  • Large capacitors are included in car audio systems to provide extra power to amplifiers when needed.
  • They are also used in utility substations to counteract inductive loading introduced by transmission lines.

Besides, in order to store charges and for different electric works capacitor are used.
