Final answer:
A GFCI is a safety device that prevents electrical shocks by detecting current loss in unintended paths. It should be used in extension cords, portable generators, and power tools to enhance electrical safety. Safety measures like GFCIs, isolation transformers, and proper wiring systems use electromagnetic induction to prevent electrical hazards.
Explanation:
A Ground Fault Circuit Interrupter (GFCI) is a safety device designed to prevent electrical shock by detecting current loss through unintended paths. It compares the current in live/hot and neutral wires and trips if there is a leakage current greater than 5 mA, ensuring safety.
Examples of devices where GFCIs should be used include extension cords, portable generators, and power tools to enhance electrical safety and prevent hazards like shocks.
These safety measures, such as GFCIs, isolation transformers, and proper wiring systems, work based on concepts like electromagnetic induction to safeguard against electrical hazards.
