Question 379Electricity & Electronics - QMED

The correct answer is C) hand-cranked generator. The component labeled "B" in the illustration EL-0093 represents a hand-cranked generator. This type of generator is commonly used as a backup power source on vessels, including those operated by the US Coast Guard, in case the main electrical system fails. The hand-cranked generator can be manually operated to provide emergency power to essential systems. The other options are incorrect because: A) a shielded lamp is not a power source, B) a bridge rectifier is an electrical component used to convert AC to DC, and D) a selsyn motor is a type of synchronous motor, not a power generator.
