Given are four inductors. L1 = 20mH, L2 = 50mH, L3 = 70mH, L4 = 65mH, i(t) = 30mA dot e^- (300/s t) 1. Find the equivalent inductance. (If you are not able to find the equivalent inductance, please use Leq = 200mH for the following questions.) 2. What is the voltage between the terminals a and b? 3. What is the total energy stored in the inductors?
