Question

how does electic fuse work.

Answer 1

.A fuse is exactly the same. It's a thin piece of wire designed to carry a limited electrical current. If you try to pass a higher current through the wire, it'll heat up so much that it burns or melts. When it melts, it breaks the circuit it's fitted to and stops the current flowing.

Answer 2

When lightning strikes, it's exciting and exhilarating—but it's scary too. It's scary because it's dangerous: leaping bolts of lightning contain huge amounts of electrical energy that are released in a fraction of a second. If lightning strikes near your home, all that electricity has to go somewhere. One place it may go is through the electrical wiring system in your home, damaging or destroying any electrical items that are plugged in at the time. It's almost impossible to stop lightning from damaging your things, and it's generally best to unplug whatever you can well before a storm arrives. Another helpful thing you can do is install surge protectors. These cheap, compact cubes and power strips help to even-out sudden peaks of electricity in the supply and reduce the chances of damage to sensitive electronic equipment. Let's take a closer look at how they work.
