Marine Electrical Systems USCG Question #540 (Set 18)

An accidental path of low resistance bypassing the intended path and allowing passage of an abnormally high amount of current is known as what?

Official USCG Answer & Rule Citation

Correct Answer: Option C — short circuit

A short circuit creates an unintended, extremely low-resistance path across a voltage source, bypassing normal load impedance. This results in massive, potentially destructive fault currents requiring immediate interruption by properly rated marine circuit breakers or fuses.
