Calculate the mutual inductance between ...

Calculate the mutual inductance between two coils when a current of 4A changing to 8A in 0.5s in one coil, induces an emf of 50 mV in the other coil.
Data : `I_(1) = 4 A, I_(2) = 8 A, dt = 0.5 s`,
`e=50 mV = 50 xx 10^(-3) V, M = ?`

Text Solution

Verified by Experts

`e=M.(dI)/(dt)`
`:.M=-(e)/(((dI)/(dt)))= -(e)/(((I_(2)-I_(1))/(dt)))`
` = - (50 xx 10^(-3))/(((8-4)/(0.5)))= 6.25 xx 10^(-3)`
`:.M= 6.025` mH
