Question

an inductor and a resistor are connected with a double pole toa battery as shown in the figure. the switch is thrown from position b to a ( connecting thebattery ). a) how much time elapses before the current reaches 218mA ? Answer in units of ms. b) what is the maximum current in the inductor a long timeafter the switch is in position a ? Answer in units of A. c) the switch has brushes within it so that the switch can bethrown from a to b without internal sparking now the switch issmoothly thrown from a to b shorting the inductor and resistor. howmuch time elapses before the current? Answer in ms.
