Calculate the mutual inductance between ...

Calculate the mutual inductance between two coils when a current 2A changes to 6A in and 0.2 s and induces an emf of 20mV in secondary coil.

Text Solution

AI Generated Solution

To calculate the mutual inductance between two coils given the change in current and the induced emf, we can use the formula for induced emf in terms of mutual inductance: \[ \text{Induced EMF} = M \cdot \frac{\Delta I}{\Delta t} \] Where: - \( M \) is the mutual inductance, ...
