- Two ideal inductors, L1 and L2, have zero internal resistance and are far apart, so their magnetic fields do not influence each other. (a) Assuming these inductors are connected in series, show that they are equivalent to a single ideal inductor having Leq = L1 + L2. (b) Assuming these same two inductors are connected in parallel, show that they are equivalent to a single ideal inductor having 1/Leq = 1/L1 + 1/L2. (c) What If? Now consider two inductors L1 and L2 that have nonzero internal resistances R1 and R2, respectively.
