Question

Explain what would happen if you used a copper penny to replace a melted fuse. Why would this happen?

Answer 1

You would get a more serious problem.  A fuse is designed to "blow" if the amount of current (electrical energy) going through it exceeds a certain amount.  This is a safety feature that prevents an electrical system from overheating and possibly catching fire, as well as to protect other parts of the system beyond the fuse.  A penny will not do this.   Yes, it will allow the current to flow through, but it will allow too much.

Answer 2

This is a very dangerous act and should not be tried.

Fuse wires are to protect your home or equipment and only the particular gauge wire should be used.

Answer 3

Your house would likely burn.  Fuses are deliberately  made to blow and cut a circuit.  Pennies are not.

The heat would continue to rise until the wire melted -- perhaps inside to wall -- breaking the circuit the way the fuse should have.

Then dial 911.
