What is the standard frequency of AC power in the United States?
Answer: 60 Hz
The US standard AC power frequency is 60 hertz (Hz), meaning the current alternates direction 60 times per second.
What does a transformer do in an electrical system?
Answer: Changes AC voltage from one level to another
A transformer uses electromagnetic induction to step up or step down AC voltage levels.
Which wire color is used for the neutral conductor in standard US residential wiring?
Answer: White
In US residential wiring, the white wire is the neutral conductor, which carries current back to the source.
What does a fuse do in an electrical circuit?
Answer: Interrupts the circuit if current exceeds a safe level
A fuse contains a metal element that melts when excess current flows, breaking the circuit to prevent damage or fire.
What is the difference between AC and DC current?
Answer: AC periodically reverses direction; DC flows in one direction only
Alternating current (AC) reverses its flow direction periodically, while direct current (DC) flows continuously in one direction.
What is a ground fault?
Answer: An unintended connection between an energized conductor and ground
A ground fault occurs when electrical current flows along an unintended path to ground, posing a serious shock hazard.
