What is the primary function of a fuse in a circuit?

• To increase the current flow

• To prevent damage due to overloading the circuit

• To store electrical energy

• To convert electrical energy to mechanical energy

What happens when the current flow in the circuit exceeds the safe maximum?

• The fuse enhances the current flow

• The fuse 'blows' and the thin wire inside becomes destroyed

• The fuse stores the excess current

• The fuse converts the excess current to heat

How are fuses typically color-coded?

• By their voltage rating

• By their current rating

• By their size

• By their material

Which type of fuse is most commonly found in all vehicles?
