Answer:
Alternate current is more useful.
Explanation:
Alternate current is usually used in household circuits as it high voltage. It has an alternating magnitude a d changes it polarity. Thus, the voltage can be decreased by a step-down transformer or can be increased by a step-up transformer, thus it can be used in many appliances according to their voltage requirements. Direct current is used in small scale circuits, as it does not require such high voltage and alternating magnitude. Overall, AC has a better hand over DC.
