The metal pieces which are welded together with the armature coil to facilitate flow of current in an AC generator are known as _____
Slip rings
An AC generator is an electric generator that converts mechanical energy into electrical energy in form of alternative emf or alternating current. AC generator works on the principle of Electromagnetic Induction.
A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. They are the metal rings which are welded together with the armature coil. A slip ring can be used in any electromechanical system that requires rotation while transmitting power or signals.
