a metal piece is cut into several pieces . The length and radius of two pieces are in the ratio 1:2.Compare the resistance of A and the equivalent resistance when A and B are connected in parallel....pls answer at the earliest. ..pls

Answer»

pieces of metal are A and B.a/c to question, ratio of length of pieces A and B is 1 : 2 and ratio of radius of pieces A and B is 1 : 2. e.g., and we know, where R is resistance, l is length of WIRE and a is cross SECTIONAL area of wire. so,  and here, we get, when both pieces are CONNECTED in parallel.then, hence,
