What is a choke coil and how is it used in AC circuits?
1 Answer. A choke coil, also known as an inductor or simply a choke, is a passive electrical component used in AC circuits to impede the flow of alternating current while allowing the passage of direct current. It is essentially a coil of wire wound around a core, often made of iron or ferrite, which increases its inductance.
