Question

A wire of resistance 20ohm is bent in the form of a closed circle. What is the effective resistance between the two points at the end of any diameter of the circle two wires A and B are of equal length, different cross-sectional area made of same metal (a) name the property which is same for both wires (b) name the property which is different for both wires (c) if the resistance of wire A is four times the resistance of wire B calculate (1) the ratio of cross sectional area of the wires (2) the ratio of the radius of the wires​
