What is a current relay?
What will be an ideal response?
The current relay operates by sensing the amount of current flow in the circuit. This type of relay operates on the principle of a magnetic field instead of expanding metal. The current relay contains a coil with a few turns of large wire and a set of normally open contacts. The coil of the relay is connected in series with the run winding of the motor, and the contacts are connected in series with the start winding.
