Question

Quizplus · Accepted Answer

The release of arc flash energy is measured in megajoules, which is a unit of energy. Millivolts and volt-newtons are units of electrical potential and work, respectively, but they do not directly measure the amount of energy released in an arc flash. Megawatts measure power, which is the rate of energy transfer, rather than the total amount of energy released.
