Solution of Question No 156 of GATE 2015 EEE Paper

Case-I

$ {\mathrm L}_{\mathrm{eff}.}={\mathrm L}_1+{\mathrm L}_2=2\mathrm L,\mathrm a=2 $

case-II

$ {\mathrm L}_{\mathrm{eff}.}=\frac{{\mathrm L}_1{\mathrm L}_2}{{\mathrm L}_1+{\mathrm L}_2}=\frac{\mathrm L^2}{2\mathrm L}=\frac{\mathrm L}2,\;\mathrm a=0.5 $

Case-III 

If both are differentially coupled then 

$ {\mathrm L}_{\mathrm{eff}.}=0 $

Minimum value = 0
