A wire of length L and cross-sectional area A has a resistance of 5 Ω. What is the resistance if the same amount of material is used to make a wire triple as long?
The resistance R of a wire of length l and uniform area of cross-section A is given by R = rhol/A, where rho is the resistivity of the wire. You melt the wire and recast it to have a new length l' = 10l (keeping the volume V = Al of the wire constant). What is the new resistance of the wire, if the original resistance of the wire was 100.0 Ohm.

Consider the rectangular prism shaped wire shown in the figure below where the cross sectional part is a square with sides d=10.1 mm. The current runs along the length of the wire where ℓ =7.3 m and the wire has cylindrical hole along its length with a cross sectional area of A=21 mm2. If the wire is made out of a material whose resistivity is 126 × 10-6Ω.m , determine the resistance of the wire. Please express your answer in...
Two copper wires have the same length but different cross sectional areas. The cross-sectional area of wire 1 is A, and that of wire 2 is 2A. How are the resistances of the two wires related? Choose the correct answer from the following choices. Wire 1 has four times the resistance of Wire 2 Wire 1 has half the resistance of Wire 2 The are the same. Wire 1 has twice the resistance of Wire 2
