Answer:


0\%

Step-by-step 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
0\% percent of the ungrounded conductor current.
