Two coils are wrapped around each other as shown in Fig. 30.3. The current travels in the same sense around each coil. One coil has self-inductance L.. and the other coil has selfinductance L2?? The mutual inductance of the two coils is M.(a) Show that if the two coils are connected in series, the equivalent inductance of the combination is Leq = L1 + L2 + 2M.(b) Show that if the two coils are connected in parallel, the equivalent inductance of the combinationis
