일반물리학 2 — Induction and Inductance: Problem 11

11 Inductors in series. Two inductors $L_1$ and $L_2$ are connected in series and are separated by a large distance so that the magnetic field of one cannot affect the other. (a) Show that the equivalent inductance is given by $L_{eq} = L_1 + L_2$. (Hint: Review the derivations for resistors in series and capacitors in series. Which is similar here?) (b) What is the generalization of (a) for $N$ inductors in series?
