In the following circuit (Figure 16), R = 1009, R = 2009, L= 10mH, Is = 0.1A. Assume the switch has been open for a long time and the switch closes at t = 0sec. Use the Nor- ton Equivalent Circuit method to solve for the equivalent parallel RL circuit. Find the Rth Ise and time constant. If the switch is closed at t > 0, determine the value I at t = 0.1ms. ro t=0 Is ww R Figure 16: Circuit 16 R IL *************
