Capacitor vs. Transistor: Difference and Comparison
Edited by Muazma Batool — By Muneeza Rehman — Published on February 12, 2024
A capacitor stores electrical energy temporarily, while a transistor regulates current or amplifies signals in electronic devices.
Difference Between Capacitor and Transistor
A capacitor is a passive electronic component that stores electrical energy temporarily in an electric field. Transistors, on the other hand, are semiconductor devices used to amplify or switch electronic signals and electrical power.

The capacitor essentially consists of two conducting plates separated by a non-conducting dielectric medium. When voltage is applied across the plates, an electric field is created, storing energy. Transistors, however, operate based on the principles of semiconductor physics. They have three terminals: base, collector, and emitter. The flow of current between the collector and emitter is controlled by the current flowing into the base.
