In the network of resistances shown in figure-3.88. ABCDA is a uniform circular wire of resistance `2Omega,AOC` and BOD are two wires along two perpendicular diameters of the circle, each having same resistance `1Omega`. A battery of-voltage E is inserted in one in one quadrant of the network as shown in figure. Calculate the equivalent resistance of thenetwrok across the battery.
