Introduction to Choke Coil
A choke coil is an inductor designed to block high - frequency alternating current (AC) while allowing direct current (DC) or low - frequency AC to pass through. It works based on the principle of electromagnetic induction. When an alternating current flows through the coil, a self - induced electromotive force (emf) is generated according to Faraday's law of electromagnetic induction, which opposes the change in the current. This property makes choke coils widely used in various electrical and electronic circuits, such as power supplies, radio frequency (RF) circuits, and audio systems, to filter out unwanted frequencies, reduce electromagnetic interference (EMI), and stabilize the power supply.
