SERIES AIDING:
Suppose two coils are in series with same place dot.
When 2 dots are at the same place of both inductors(while at entering place or leaving
place)as shown in below figure i.e. the total mutual inductance gets aided(added)
Mutual inductance
between them is positive.
SERIES OPPOSING:
Suppose two coils are in series with opposite place dot.
When 2 dots are at the opposite place of both inductors(while one at entering place and
other at leaving place)as shown in below figure i.e. the total
mutual inductance gets
differed
