Question

what is an electric fuse?why is it advised to use three pin plugs while using power applications?

Answer 1

Electric Fuse

In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby interrupting the current.

Grounding

The reason that some plugs come with three pins is that they are "grounded." This means that the third pin connects directly through a series of wires to the ground outside of the building. In case of an electrical problem, you don't want the electricity seeking to ground inside your home, as this could cause a fire; it is safer to have it grounded outside.

I hope this helped you!!! :)
