What is an element in an electrical circuit which serves as a protection against overload? Correct Answer Fuse

Fuse:

• A fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. 
• Fuses are widely used for the protection of electric motor circuits against small overloads and short circuits.
• The motor protection circuit will open the controlling contactor automatically, and the fuse will only operate for short-circuits or extreme overload.

Resistance:

The property of any conductor that opposes the flow of electric current through it is called resistance.

Mica

1. Mica is a naturally occurring non-metallic mineral that is based on a collection of silicates. 

2. Mica is used extensively in the electrical and electronic industry because of its dielectric strength and insulating properties.

Semiconductor:

Semiconductors are those elements that conductivity lies between conductor and insulator.
