Explanation
The self-induced voltage in a coil depends on the rate of change of current, the number of turns, and the magnetic path properties. However, the voltage applied to the coil itself does not directly affect the self-induced voltage, as it is determined by the coil's current and magnetic characteristics rather than the external voltage.
