By what means is electric current conveyed to the electric drive motor of a podded propulsor?

Correct Answer: Option C — Current is conveyed from the source to a set of stationary brushes, then through a set of rotating slip rings and then on to the motor windings.

Podded propulsors require power transmission to a rotating unit. Current is transferred from stationary brushes to rotating slip rings mounted on the pod shaft. This arrangement ensures a continuous electrical connection to the internal drive motor while allowing the entire pod to rotate for steering and maneuvering purposes.
