Question

Abcd is a square where each side is a uniform wire of resistance 1ohm. Find a point e on cd

Answer 1

ABCD is a square where each side is a uniform wire of resistance 1 ohm. What are the coordinates of point E on CD such that if a uniform wire of resistance 1 ohm is connected across A&E points B and E will be equipotential? The key to the soln is that the ratio of resistance to both sides of B and E should be the same.
