Question

a uniform wire is cut into four segment each segment is twice as long as the earlier segment is the shortest segment has the resistance of 2 ohm find the resistance of the original wire​

Answer 1

Answer:

hey mate

Explanation:

Let the lengths of segments be x,2x,4x and 8x

cutting into two segements doesn't effect resistivity and area of cross section

so for x length the resistance is 4 ohm

so the length of original segment is x+2x+4x+8x=15x

so the resistance is 60 ohm
