Question

An inductor L= 239 mH and a resistor R = 6.4 ohms are connected with a double pole switch to a battery E = 5.6 v, as shown in the figure. The swithc has been in the "b" position for a long period of time Note that the values here are demostrative, use your own set. 2.88 ? 111 mH Sb www0000 5.2 V a)If the switch is thrown from the position "b" to the position "a" connecting the battery, how much time elapses before the current reaches 97 mA?. Note: answer in ms. t1 = ms. b) What is the maximum current in the inductor a long time after the switch is in position "a"? I= A. c) The switch has brushes within it so that the switch can be thrown from "a" to "b" without internal sparking. Now the swithc is smoothly thrown from "a" to "b", shorting the inductor and the resistor. How much time elaspses before the current falls to 140 mA? t2= ms.
