WebApr 30, 2024 · The rate of change of current in an inductor is proportional to the applied voltage. In order for the current to change instantaneously, you would need to apply infinitely great voltage for a short time--an impulse of voltage, in other words. Thus, first you need to do is "discharge" the inductor. \$\endgroup\$ – WebApr 7, 2011 · Capacitors inhibit the flow of electrons, resulting in exponential growth of potential to the peak value, at the expense of exponential decay of current. While discharging, the opposite occurs, the charge just decreases gradually, goes through the resistor, and out the ground. I don't know much about inductors.

WebAn inductor: A lower resistance means that it will take longer for the inductor to discharge. Theoretically, infinitely small resistance means that the inductor will discharge forever Higher resistance means it will take less time for the inductor to discharge. But then I was thinking that the lower the resistance, the higher the power ...
