Electromagnetic Induction - Inductors Connected in Series and Parallel

Inductors Connected in Series

Current remains same in both the coils. The induced emf in both coils is given below



Let e be the induced emf of  equivalent inductor of  equivalent inductance L.






Inductors Connected in Parallel

In parallel combination current distributes its self

Differentiates both sides with respect to time.
 ---equation 1

Since both coils are connected in parallel so potential remains same. 
 ---equation 2


 ---equation 3

 ---equation 4


Substitute values from equation 2,3,4 in equation 1

Electromagnetic Induction - Mutual Induction

As we have variable source with increasing current in primary coil ,there will be a flux change in primary coil. Due to this flux change in primary coil there will be a flux change in secondary coil and this flux change in secondary coil will generate induced emf in secondary coil. This is called mutual induction. flux linked with secondary coil depends on current in primary coil ,so they are directly proportional to each other. differentiate with respect to time both sides   ------equation 1 As per faraday law induced emf in secondary coil is  ------equation 2 substitute value from equation 1 to equation 2   Visit PHYSICS page for more blogs
