Answer & Explanation

Correct AnswerB. In phase with the arc current

Quick Explanation

For a purely resistive arc path, voltage and current have no reactive phase displacement. Therefore the arc voltage is in phase with the arc current.

B — In phase with the arc current

For a purely resistive arc path, voltage and current have no reactive phase displacement. Therefore the arc voltage is in phase with the arc current.
