Question

Two coil having self inductances L= 75mH and L2 = 55mH are coupled with each other. The coefficient of coupling(K) is 0.75, calculate the Mutual inductance(M) of the two coils.

Answer 1

$$\begin{gathered} DearStudent \\ MutualInduc\tan ce=k*\sqrt{L_1{L}_2} \\ MutualInduc\tan ce=0.5*\sqrt{(8*18)} \\ M=0.5*\sqrt{\left(144\right)} \\ M=0.5*12 \\ \mathit{M}\mathbf{=}\mathbf{6} \\ \mathit{R}\mathit{e}\mathit{g}\mathit{a}\mathit{r}\mathit{d}\mathit{s} \end{gathered}$$
