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 self - induction. When an alternating current flows through the coil, a changing magnetic field is generated, which in turn induces an electromotive force (EMF) that opposes the change in current. Choke coils are 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 improve the stability and performance of the circuits.
