Question 1 of 5
Fuses

Fuses are thin wires that melt when the current in a circuit exceeds a preset amount. They help prevent short circuits from damaging circuit components when an unusually large current is applied to the circuit, either through component failure or spikes in applied voltage.

Using a fuse with a current rating higher than that required by a circuit:

is required

makes the circuit less safe

is recommended

makes no difference
