B) amp spike
C) wattage jolt
D) voltage spike

Question

Quizplus · Accepted Answer

This is known as a voltage spike, also referred to as a back-EMF or flyback voltage, and occurs when the current flowing through an inductor is suddenly interrupted, causing a high voltage pulse in the opposite direction of the original current flow. This can be problematic in electronic circuits and can be mitigated with diodes or other protective measures.
