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

Show Suggested Answer Hide 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.

I’m confused; I thought lighting could also use both types of current. Is it really just electrolysis that needs DC?

I practiced a similar question, and I believe turning a motor can work with AC, so I’m leaning towards D too.

This looks like a straightforward question about the capabilities of the SVP Performance Monitor. I'll need to carefully read through the options and think about which two purposes the tool is best suited for.
