3. CONTENT  INDUCTANCES IN SERIES  EXAMPLE  INDUCTANCES IN PARALLEL  EXAMPLE

4.  When the coils are so connected that the end of coil one is connected to the starting of second coil and so on as to form a shape of a chain, these are connected in series. In this case the flux of first coil does not effect the second coil at all.  Let their inductances be Ll and L2 and are connected across E volt of f- frequency. In that case when same current is flowing in hoth the coils. Inductance in series

5. IIt is a very ideal case. But in actual prac- tice the mutual induction takes place and let M be the Coefficient of mutual induc- tion. Than equivalent inductance. IIf both the coils are connection in such a way as to result a additive mmfs than equivalent inductance is IIf both the coils are connected in such a way as to result a subtractive mmfs than equivalent inductance is

6. EXAMPLE  Inductors in series  All have the same current

7.  To determine the Equivalent inductance

8.  The Equivalent Inductance

9.  When inductors are connected in parallel, the reciprocal of the equivalent inductance of the combination will be the sum of individual inductances’ reciprocal.  This is just like the equivalent resistance of parallel-connected resistors. We may also have to consider the effect of mutual inductance in the same way if required.resistanceparallel-connected resistors Inductance in parallel

10.  We will learn the effect of mutual inductance on parallel inductors later in this article. Without considering the effect of mutual inductance, we can write, An inductor is passive circuit element.

11. EXAMPLE  Inductors In Parallel  All Inductors have the same voltage across their terminals

14.  Summary for inductors in parallel
