The total current supplied to the distributor is (i × l). As the two end voltages are equal, therefore the current supplied from each feeding point is
Current supplied from each feeding point =
Consider a point C at a distance x meters from the feeding point A. The current at point C is:
Now, consider a small length dx near point C. Its resistance is r dx and the voltage drop over length dx is:
The voltage drops up to point C:
The point of minimum potential will be the mid-point. Therefore, the maximum voltage drop will occur at mid-point i.e. where x = l/2.
