If it is connected in series combination let we have to imagine it can be divided as 3
so
Lt=L1+L2+L3
I.,e LT= 3*28=84

M1, M2, M3 are the mutual inductances.
Leq= L1+L2+L3
�2M1
�2M2
�2M3
The sign conventions depend upon the dots. If dots of both mutual inductors are at positve/negative potential
like dot of L1 is at +ve terminal while the dot of L2 is at +ve terminal
then addition is done & if the dots of both mutual inductors are at either potential, like dot of L1 is at +ve terminal while the dot of L2 is at -ve terminal then subtraction is done.
