In Fig. coil 1 and coil 2 are wound on a long cylindrical insulator. The ends A' and B are joined together and current I is passed. Self-inductance of the two coils are L_(1) and L_(2) , and their mutual inductance is M . a. Show that this combination can be replaced by a single coil of equivalent inductange given by L_(eq) = L_(1) + L_(2) + 2M . b. How could the coils be reconnected by yieldings an equivalent inductance of L_(eq) = L_(1) + L_(2) - 2M .
