APC Exam DU0-001 Topic 2 Question 95 Discussion

Actual exam question for APC's DU0-001 exam

Question #: 95
Topic #: 2

What is the advantage of a three-phase power source versus a single-phase

power source?

AThree-phase power delivers balanced voltage across all three-phases.

BThree-phase power delivers up to three times the amount of power of a
single-phase power source.

CThree-phase power cancels neutral harmonics on the 3rd, 5th, and 7th
orders where Single-phase power does not.

DThree-phase power does not require a neutral; therefore, you can attain
increased levels of efficiency over single-phase power.

Three-phase power? More like three-times the confusion if you ask me. I'll stick to my trusty single-phase toaster oven, thank you very much.

Hmm, I'm not sure. This question is giving me a headache. Maybe I should've studied more on electrical theory instead of watching cat videos.
