Question

Quizplus · Accepted Answer

To completely collapse an inductor's magnetic field, it theoretically takes an infinite amount of time. However, for practical purposes, 5 time constants are considered sufficient for the current to decrease to less than 1% of its initial value, effectively collapsing the magnetic field.
