Which item does not prevent electrical accidents?

a. superconductor

b. ground-fault circuit interrupter

c. fuse

d. circuit breaker

Hello there!

The fuse, circuit breaker and ground-fault circuit interrupter are things that broke when the current is high enough, cutting the circuit in the process and prevent possible electrical accidents.

A superconductor, for the other hand, is a very good conductor with almost zero resistance, this has nothing to help prevent electrical accidents, it is just a very very good conductor.
