A 12.0 V battery is connected into a series circuit containing a 20.0 A resistor and a 1.90 H inductor. (a) In what time interval (in s) will the current reach 50.0% of its final value? 0.065844 (b) In what time interval (in s) will the current reach 90.0% of its final value? 021869 What If? After a very long time, using a switch like that shown in the figure below, the battery is removed and the inductor is connected directly across the resistor. R S2 (c) In what time interval (in s) will the current decrease to 50.0% of its initial value? (d) In what time interval (in s) will the current decrease to 10.0% of its initial value?
