Capacitors are components that store electricity and electrical energy (potential energy). A conductor is surrounded by another conductor, or the electric field lines emitted by one conductor are all terminated in the conductor system of another conductor, called a capacitor. The role of capacitors is: ●Coupling: The capacitor used in the coupling circuit is called the [...]
