The difference between a 5 amp fuse and a 10 amp fuse is the amount of current they can safely carry. A 5 amp fuse is designed to break the circuit if the current flowing through it exceeds 5 amps, while a 10 amp fuse is designed to break the circuit if the current exceeds 10 amps.
If you replace a 5 amp fuse with a 10 amp fuse, the fuse will not blow as quickly when there is a fault in the circuit, and this can lead to damage to the circuit components or even a fire.
It is important to use fuses with the correct amperage rating as specified for the circuit. If you are not sure of the correct amperage rating for a fuse, it is best to consult with an electrician.
