1.	A metal wire of resistance 3Ω is elongated to make a uniform wire of double its previous length. The new wire is now bent and the ends joined to make a circle. If two points on this circle make an angle 60º at the centre, the equivalent resistance between these two points will be: (A) (12/5)Ω(B) (5/3)Ω(C) (5/2)Ω(D) (7/2)Ω
Answer» ANSWER: (C) (5/2) ohom. that is RIGHT answer.
