A wire of resistance 9Ω is bent in a form of equilateral triangle. The equivalent resistance between any two of its vertices will be :
Three resistors having resistances 2 Ω, 3 Ω and 4 Ω are connected so that the equivalent resistance is 9 Ω. The resistors are connected in:
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
