Question

Which of the following statement is NOT true about GFCI (ground fault circuit interrupter) outlets GFCI outlets depend upon a magnetic induction effect to "trip the switch". GFCI outlets are often found in homes in rooms where water is presen GFCI outlets cut power to the circuit if they detect that the current leaving the outlet is no longer equal to the current returning to the outlet. If a hairdryer is connected to a GFCI outlet, under normal operating conditions, a substantial magnetic field could be measured around the wire leading to the hairdryer.

Answer 1

The statement that GFCI outlets depend on a magnetic induction effect to trip the switch is not correct. These outlets monitor the balance of electrical current and quickly trip if there is an imbalance, typically in situations where electrical shock is occurring. GFCI outlets are commonly found in rooms where water is present.

Step-by-step explanation:

The statement 'GFCI outlets depend upon a magnetic induction effect to 'trip the switch'' is NOT true about GFCI (ground fault circuit interrupter) outlets. GFCI outlets monitor the balance of current between the hot (live) and neutral wires. When there is an imbalance, such as would occur if a person were being shocked, they quickly trip and de-energize the circuit. The tripping mechanism of a GFCI outlet is not based on a magnetic induction effect.

In most cases, GFCI outlets are found in rooms where water is present as they add a layer of protection against electrical shock. Furthermore, under normal conditions, if a hairdryer is connected to a GFCI outlet, the magnetic field around the wire leading to the device would not necessarily be substantial.
