How can you determine if a fuse is faulty?

• Visually inspect the fuse
• Test the continuity of the fuse using a multimeter
• Replace the fuse and check if the circuit works
• Measure the voltage across the fuse

What does a "short circuit" refer to in electrical systems?

• A circuit with too much resistance

If a circuit breaker keeps tripping, what could be the possible cause?

• Overheating of the circuit breaker
• Faulty wiring in the circuit
• Power surge from the utility provider
• Incorrect circuit breaker rating

What is the purpose of a ground fault circuit interrupter (GFCI)?

• To protect against overvoltage
• To prevent electrocution in the case of a ground fault
• To measure the voltage in a circuit
• To regulate the flow of current in a circuit
