Which risk increases when a three-ampere fuse protects a five-ampere circuit?

💡 Explanation

The risk increases of overheating of circuit conductors because the circuit can sustain a higher current than optimal due to the fuse's current beyond the protection limit; therefore, thermal runaway becomes possible rather than an appropriate safety shutdown.
