Two coils connected as shown in Fig. 30-48 separately have inductances L_(1) and L_(2). Their mutual inductance is M. (a) Show that this combination can be replaced by a single coil of equivalent inductance given by L_(eq)=L_(1)+L_(2)+2M (b) How could the coils in Fig. 30-48 be reconnected to yield an equivalent inductance of L_(eq)=L_(1)+L_(2)-2M? |
| Answer» SOLUTION :(b) have the turns of the two SOLENOIDS wrapped in OPPOSITE DIRECTIONS, `L_(eq)= L_(1) + L_(2)- 2M` | |
