Question

if length of a wire decrease to half of its length .what is the effect on resistance if intial resistance is one ohm?????​

Answer 1

Heya mate...

Resistance is directly proportional to area and inversely proportional to length. Hence if we increase resistance we get increased area and decreased length and vice - versa. Also Resistivity wont change if the length and area is changed. It remains constant for all values for a given material
