E xplain why the build-up current of an inductor reaches its steady state the end of 5 time constants . C alculate the build-up current through an inductor after a given number of time constants. E xplain why the decaying current of an inductor reaches a steady state at the end of 5 time constants .
C alculate the amount of decay current through an inductor after a given number of time constants.
I O N RL Build-Up Curve Current through the inductor in an RL circuit does not increase at a steady rate. Rather, the rate of increase is rapid at first, but then slows as it reaches the maximum level. Inductor current build-up is considered complete at the end of 5 time constants . RL Decay Curve Inductor current does not drop off at a steady rate. Rather, the rate of current decay is discharge is rapid at first, but slows considerably as the charge approaches zero.
