ABCD is a square where each side is a uniform wire of resistance `1 Omega`. Find a point E on CD such that if a uniform wire of resistance `1 Omega` is connected across AE and a constant potential is applied across A and C, the points B and E will be equipotential.

In figure. ABCD is a square where side is a uniform wire of resistance 1Omega . Find the a point E on CD such that if a uniform wire of resistance 1Omega is connected across AE and a constant potential differene is applied across A and C the points B and E are equipotential.

ABCD is a square where each side is a uniform wire of resistance 1Omega. A point E lies on CD such that if a uniform wire of resistance 1Omega is connected across AE and constant potential difference is applied across A and C, then B and E are equipotential.
