When a conductor is stretched, its length becomes double. Find out how many times the resistance changes.​

Answer»

e wire is STRETCHED to double the length , the area of CROSS section gets reduced to HALF. So when the wire is stretched to 2 times , the resistance multiplies by four times.____________________________________Information about resistance :Resistance is directly proportional to the length of the wire.Resistance is inversely proportional to the area of cross section of the wire
