일반물리학 2 — Induction and Inductance: Problem 63

63 The inductor arrangement of Fig. 30-50, with \(L_1 = 50.0 \text{ mH}\), \(L_2 = 80.0 \text{ mH}\), \(L_3 = 20.0 \text{ mH}\), and \(L_4 = 15.0 \text{ mH}\), is to be connected to a varying current source. What is the equivalent inductance of the arrangement? (First see Problems 11 and 50.)
