Three resistors (r1 = 120 ohms, r2 = 330 ohms, and r3 = 240 ohms) and an ideal inductor (l = 1.6 mh) are connected to a battery (v = 9 v) through a switch as shown in the figure below.
the switch has been open for a long time before it is closed at t = 0. at what time t0, does the current through the inductor (i3) reach a value that is 63% of its maximum value?
