A wire of uniform cross-section and length `l` has a resistance of `16 Omega ` is cut into four equal parts. Each part is stretched uniform to length `l` and all the four stretched parts are connected in parallel calcuate the total resistance of the combination so formed. Assume that stretching of wire does not cause any change in the density of its material

A wire of uniform cross section and length l has a resistance of 16 Omega . It is cut into four equal parts.Each part is stretched uniformly to length l and all the four streteched parts are connected in parallel. Calculate the total resistance of the combination so formed. Assume that stretching of wire does not cause any change in the density of its material.

A wire of uniform cross section has a resistance of 9 Omega. It is cut into three equal pieces. Each piece is stretched uniformly to three times its length and all the three stretched pieces are connected in parallel.Assuming that stretching of wire does not cause any change in density of their material ,calculate the total resistance of the combination described.
