so that its radius is halved. Compare the new

Answer:
resistance is twice the original wire
Explanation:
because volume is same in both the cases and the radius halved hence the area of cross-section decreases and length of conductor increases
thus resistance increase as resistance is directly proportional to length of conductor and inversely proportional to area of cross-section
