In a sinking ship, when the water rushes in, the lights are kept on since one cannot evacuate in the dark. How does one manage to keep the electricity running without getting an electric shock, as water is a good conductor?

Here’s a hint:

Salt water conducts electricity much better than the human brain. In such circumstances, electricity will flow through salt water and not through the human body.

Electrical accidents caused by faulty wiring in a dock are a problem in saltwater environments but not in freshwater environments.

I don’t know if electrical shock is a high risk in fresh water sinkings. It is not likely to pose a problem in saltwater.
