C. Alternating current (AC).
D. Direct current (DC).



Answer :

GinnyAnswer

Final answer:

HVACR systems primarily operate on alternating current (AC) due to its periodic voltage variation, contrasting with direct current (DC) systems which have a constant voltage source.


Explanation:

Most HVACR systems operate on alternating current (AC). Direct current (DC) systems have a constant source voltage, while AC systems' voltage varies periodically, typically sinusoidally. AC is used in residential applications, and it allows for the easy transformation of voltage using transformers.
