What is the function of a GFIC receptacle?

• A. To increase voltage
• B. To protect against electrical shocks
• C. To control lighting fixtures
• D. To measure current

Answer: (B)

A Ground Fault Circuit Interrupter (GFCI) receptacle plays a crucial role in electrical safety by protecting against electrical shocks. It does this by continuously monitoring the amount of current flowing through the circuit. If it detects an imbalance between the outgoing and returning current, which could indicate a ground fault or current leakage, the GFCI rapidly disconnects the electricity to prevent injury. This function is especially important in areas where there is a higher risk of electrical shock, such as kitchens and bathrooms, where water is commonly present. The other options describe functions that are not relevant to the GFCI receptacle. Increasing voltage pertains to devices like transformers. Controlling lighting fixtures is more applicable to dimmer switches or smart lighting controls, and measuring current would typically involve ammeters or similar electrical measuring devices. The primary and most significant purpose of a GFCI is to ensure safety by minimizing risk from electrical hazards.
