Question 310Electricity & Electronics - QMED

The correct answer is A) first speed. In the illustration EL-0073 of the elementary diagram of a three-speed anchor windlass controller, the contactor, relay, or timer coil that operates with DC voltage is the one for the first speed. This is because the anchor windlass is typically powered by a DC electrical system on board a vessel, and the first speed is the most basic and direct connection to the DC power source. The other options, B, C, and D, likely represent higher speed or more complex control circuits that may operate on AC voltage or use additional relays and timers, but the fundamental first speed contactor or relay is the one that is directly powered by the DC voltage of the vessel's electrical system.
