Group Problem 2: You are given the task to determine the inductance M of two inductors of unknown self-inductances L1 and L2. Recall that M = M12 = M21 and the magnetic flux B1,2 = M12/1 and B2,1 = M2112. To perform this task, you connect one of the inductors (say L1) in series with a battery of emf = 10 V and a resistor of resistance R1 = 212. These three components, as well as a switch S, form...
