Answer 1

Answer:

when length of a wire is doubled ,its resistance gets doubled and if the length is halved then its resistance gets halved.

hope it helps.

Answer 2

Complete answer:

So, the new resistance, after doubling the length of the wire, becomes twice of the original resistance. Hence, if the length of a wire is doubled, then its resistance becomes doubled.
