Extracted text: When the voltage source is turned off in a simple circuit consists of a resistor and an inductor, the rate of decrease of the current is proportional to the current. The current is 40 amperes at the moment that the switch is off and dies down to 15 amperes after 0.01 sec. Determine the current in 0.02 sec. 3.375 amperes 4.25 amperes 5.625 amperes 6.025 amperes
