Final answer:
Receptacles in bathrooms must be GFCI protected, which is true, to prevent electric shock by quickly responding to electrical faults and tripping the circuit.
Step-by-step explanation:
Receptacles in bathrooms must be GFCI protected. This is true. A Ground Fault Circuit Interrupter (GFCI) is an essential safety device installed in residential and commercial bathrooms to prevent electric shock. GFCIs work by comparing currents in the live/hot and neutral wires and tripping the circuit if they detect a leakage current greater than 5 mA.
This quick response to changes in current helps prevent electrocution by cutting off electricity in the event of a fault. It is important that GFCI protection be present because the bathroom environment presents an increased risk of electrical accidents due to the presence of water.
