Which outcome occurs when current through a transformer's primary circuit abruptly ceases?

💡 Explanation

A sudden stop in primary current leads to a large voltage spike because the transformer experiences inductive kickback as the collapsing magnetic field attempts to sustain the current flow, therefore a dangerous voltage surge occurs rather than diminished eddy currents.
