With regard to the coupled inductors shown in Fig. 13.53, L1 = 10 mH, L2 = 5 mH, and k =

Chapter 13, Problem 25

(choose chapter or problem)

With regard to the coupled inductors shown in Fig. 13.53, \(L_1 = 10\ mH\), \(L_2 = 5\ mH\), and k = 0.75. (a) Compute M. (b) If \(i_1 = 100\ sin\ 40t\ mA\), and \(i_2 = 0\), compute the energy stored in each coil and in the magnetic field coupling the two inductors at t = 2 ms. (c) Repeat part (b) if \(i_2\) is set to \(75\ cos\ 40t\ mA\).
