Calculate the mutual inductance between ...

Calculate the mutual inductance between two coils when a current of `4 A` changes to `12 A` in `0.5 s` in primary and induces an emf of `50 mV` in the secondary. Also, calculate the induced emf in the secondary if current in the primary changes from `3 A` to `9 A` is `0.02 s`.

Text Solution

Verified by Experts

`:'M=e_2/(di_1//dt)=((50xx10^-3))/((8//0.5))`
`=3.125xx10^-3H=3.125mH`
`e_1=M((/_\i_2)/(/_\t))=((3.125xx10^-3)(6))/0.02`
`=0.9375V`
