When to use choke?
A choke is basically an inductor. It is used when you want to limit an alternating current without increasing the resistance of the circuit, which could lead to heat dissipation.
What is an automatic choke carburetor?
An automatic choke is a device that is mounted on the carburetor of a gasoline engine.

What is the function of a choke in a generator?
Q: What is the function of a choke in a generator?
