Question

the length of wire is doubled l. how is it's resistivity affected?​

Answer 1

Answer:

Resistance is directly proportional to the length of the wire, and inversely proportional to the cross sectional area of the wire. ... Doubling the length will double the resistance, but the wire also must get thinner as it is stretched, because it will contain the same amount of metals in twice the length.

Answer 2

Hey champ!!!!

If the length of the wire is doubled, resistivity remains unchanged.

• If the length of the wire is doubled, resistivity remains unchanged.Resistivity does not depend upon the length of wire.

Hope it helps!!!!!!!!
