Question

# Two infinite strips of width w m in X-direction as shown in figure, are carrying forward and return currents of +I and −I in the Z-direction. The strips are separated by a distance of x m. The inductance per unit length of the configuration is measured to be L H/m. If the distance of separation between the strips is now reduced to 1/2 m, the inductance per unit length of the configuration is

Solution

## The correct option is C L/2 H/mAns : (c) Inductance/m is proportional to separation between the strips so when separation is reduced to 1/2 then inductance will become L/2 H/m.
