The length of a certain wire is kept same while its radius is doubled. what is the change in the resistance of this wire?
Answers: 1
is the resistivity of the material, L the length of the wire and A its cross-sectional area. 
and L remain the same, while A changes because the radius changes. The area is given by:
of its original value.
