The Fundamentals of Capacitors in AC Circuits

Capacitors in AC circuits play a crucial role as they exhibit a unique behavior known as capacitive reactance, which depends on the capacitance and the frequency of the applied AC signal. Capacitors store electrical energy in their electric fields and release it when needed, allowing them to smooth voltage variations and filter unwanted frequencies. They are

While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed specifically to add capacitance to some part of the circuit. The physical form and construction of practical capacitors vary widely and many types of capacitor are in common use.
