What will be the resistance if the radius is doubled

Answers

Answered by smartyyash7

Resistance (R) is inversely proportional to Area(A). So if radius is doubled, new area= 4x Area of original wire. So radius being doubled means length is compromised. Doubling radius will change the length of wire to 1/4th.
