Inductors  in parallel

If there is no mutual inductance among the 2 or more parallel connected inductors, their values add up like in similar fashion as values of resistors in parallel. Suppose you have inductances L1, L2, L3, ..., Ln all connected  in parallel. Then you can find the reciprocal of total inductance, 1/L, by using following formula:

1/L    1/L1   1/L2   1/L3  ...    1/Ln

The total inductance, L, is found by taking reciprocal of number you obtain for 1/L.

Again, as with inductances in series, it is essential to remember that all the units have to agree. Do not mix microhenrys with millihenrys. The units you use for the individual component values will be the units you get for final answer.
