Question

select the choice that best completes the following statement.
a ground fault circuit interrupter monitors:
a) power lines
b) batteries
c) electrical circuits
d) hazards

Explanation:

A ground - fault circuit interrupter (GFCI) is an electrical safety device. Its main function is to monitor electrical circuits. It detects imbalances in the current flow within the circuit. If it senses a ground - fault (a situation where current is leaking to the ground), it quickly interrupts the circuit to prevent electrical shocks. Power lines are part of the electrical distribution system but are not what the GFCI specifically monitors in terms of its core function. Batteries are a source of electrical energy and not the focus of a GFCI's monitoring. Hazards is a very broad term, and the GFCI has a specific, technical monitoring target related to electrical circuits.

Answer:

C. Electrical circuits
