What is the function of a circuit breaker?
Correct!
Wrong!
Circuit breakers protect electrical circuits by interrupting current flow during faults.
Which device steps down voltage for household use?
Correct!
Wrong!
Transformers reduce high voltage to safer, usable levels.
What does a ground fault circuit interrupter (GFCI) do?
Correct!
Wrong!
It protects against electric shock by interrupting power during ground faults.
Which component stores electrical charge temporarily?
Correct!
Wrong!
Capacitors store and release electrical energy as needed.
What is the role of wiring in electrical systems?
Correct!
Wrong!
Wiring connects components and carries electrical current safely.
What device protects circuits from overload by melting?
Correct!
Wrong!
Fuses break circuits by melting when current is too high.
