The mutual inductance between two coils ...

The mutual inductance between two coils is 2.5 H. If the current in one coil is changed at the rate of `1 As^(-1), what will be the emf induced in the other coil?

Text Solution

Verified by Experts

`L=2.5H`
`(di)/(dt)=(A)/(s')`
`E=(di)/(dt)`
`impliesE=2.5xx1=2.5V`.
