Final answer:
Aircraft fuses are rated in amperes (or amps) required for proper operation. Amperes are the units used to measure electric current.
Step-by-step explanation:
Fuses in aircraft are rated in amperes (or amps) required for proper operation.
The ampere (A) is the unit used to measure electric current, which represents the flow of charge.
Most electrical appliances, including fuses and circuit breakers, are also rated in amperes.
For example, if an aircraft fuse has a capacity of 10 amps, it means that it can safely carry a current of up to 10 amps without overheating or causing damage.
