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.

Energy Stored in an Inductor

Energy in an Inductor. When a electric current is flowing in an inductor, there is energy stored in the magnetic field. Considering a pure inductor L, the instantaneous power which must be supplied to initiate the current in the inductor is. Using the example of a solenoid, an expression for the energy density can be obtained.
