Answer:
Explanation:
A 3-wire, 120/ 240 V circuit from a three-phase delta transformer contains two ungrounded conductors and one grounded conductor. The grounded conductor carries the unbalanced current when the circuit is not balanced.
A neutral conductor has the same equal potential between it and all ungrounded conductors of a 3-wire system.
The current on the neutral conductor is
percent of the ungrounded conductor current.
