For which one of these processes is Direct Current essential, and will not work with alternating current?

CTurning a motor

DElectrolysis

Show Suggested Answer

Suggested Answer: A

Whenever electrical power is being consumed in an IT room or data center, heat is generated. This heat must be removed in order to maintain an optimal temperature for the equipment, and this is usually done through cooling systems such as air conditioning, air economization, liquid cooling, evaporative cooling, and immersion cooling.

Hmm, I think it's B) Lighting. Alternating current just doesn't cut it for that.
