Question

# A 15-A fuse blows repeatedly. Why is it dangerous to replace this fuse with a 25-A fuse?

Solution

1 of 3

When there is a 15-A fuse connected to the circuit, this means that the circuit can not handle an electrical current $I$ more than 15 A.

So, it is dangerous for the circuit to raise its current more than 15 A. When you replace this fuse with 25-A, the circuit will not break if the current highly increased until it reaches 25 A.

This is dangerous for the circuit and the devices connected to it since it is designed to handle a maximum current of 15 A.

This will make more current to flow which means that the wires carrying the current will be hotter.

Hotter wires may cause fire or devices damage.
