The resistance of a wire is R . If the length of the wire is doubled by stretching, then the new resistance will be

The length of a wire is doubled by pulling it.Find the new resistance.

" The resistance of a wire is "20Omega" .It is stretched so that the length becomes double,then the new resistance of the wire will b "

The resistance of a wire is 20 ohm . It is so stretched that the length becomes three times, then the new resistance of the wire will be

The resistance of a wire is R ohm. If it is melted and stretched to n times its original length, its new resistance will be

If the length of a conducting wire be doubled by stretching, its resistance compared to the initial value will be :

A conducting wire of length 1 has resistance R. If its length is increased to nl by stretching it uniformly, what would be the new resistance of wire ? (Assume that there is no change in the volume of the wire when it is stretched.)
