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

A metal wire has a resistance of 35Omega . If its length is increased to double by drawing it, then its new resistance will be

The resistance of wire is 100Omega . If it is stretched to 4 times its original length , then its new resistance will be

The length and readius of a wire is l and r respectively. Its resistance is R. After hammering the radius of the wire is made (r/2) then the new resistance will be

" 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 wire is 20 Omega . The wire is stretched to three times its length. Then the resistance will now be

If the length of a wire is doubled by taking more of wire, what happens to its resistance?

Resistivity of a material of wire is 3 * 10^(-6) Omega-m and resistance of a particular thickness and length of wire is 2 Omega . If the diameter of the wire gets doubled then the resistivity will be
