Question

A wire of resistance R ohm is stretched to n times its original length. What is:
1) its new resistance
2) it's new resistivity

Answer 1

hii

A wire of resistance R is stretched till its length becomes n times its original length what will be its new resistance

The resistance R is directly proportional to lenght of a wire and inversely proportional to it's cross sectional area. ... The new resistance of the wire becomes four times its old resistance. The wire's length is stretched to twice its length I.e.

hope it helps (:
