A wire of resistance 18 ohm is bent to form an equilateral triangle. The resistance across any two vertices of the triangle is (in ohm):
A wire has a resistance of 6 ohms. It is bent in the form of an equilateral triangle. The effective resistance between any two corners of the triangle is
Three resistors each of 4 Ohm are connected in the form of an equilateral triangle. The effective resistance across any two corners is:
