A ground fault circuit interrupter (GFCI) works by:

Select one:

A. Measuring the voltage.

B. Measuring the amp draw.

C. Comparing the voltage to the amp draw.

D. Comparing the current on both legs of the circuit.



Answer :

Final answer:

A detailed explanation of how a GFCI works to protect against current leakages.


Explanation:

A ground fault circuit interrupter (GFCI) works by comparing the currents in the live/hot and neutral wires. When these currents are not equal, indicating a leakage current, the GFCI trips to interrupt the circuit and prevent potential hazards. It operates based on electromagnetic induction by detecting the imbalance in current flow.
