Question

What is choke coil ?​

Answer 1

Answer:

In electronics, a choke is an inductor used to block higher-frequency while passing direct current (DC) and lower-frequencies of alternating current (AC) in an electrical circuit. ... The name comes from blocking—"choking"—high frequencies while passing low frequencies.

Answer 2

Answer:

A choke coil is an inductance coil of very small resistance used for controlling current in an a.c. circuit. If a resistance is used to control current, there is wastage of power due to Joule heating effect in the resistance. On the other hand there is no dissipation of power when a current flows through a pure inductor.
