Temperature Variance of Resistance

Electrical resistance or simply resistance is the property of a material that opposes the free flow of electrons through it. The total amount of resistance to the flow of charges (or current) is affected by many factors like the length of the conducting material, its cross-sectional area, resistivity, and temperature.

At the same temperature, two wires made of pure copper have different resistances. The same voltage is applied at the ends of each wire. The wires may differ in ( check all that apply) _ a. length _b. cross-sectional area _c. resistivity _d. amount of electric current passing through them Hint 1) The resistivity of a metallic conductor, such as copper, nearly always increases with increasing temperature. Hint 2) For an ohmic conductor, that is, a conductor such as copper that obeys Ohm's law, the resistance R is proportional to the length L and inversely proportional to the cross-sectional area A. That is, R=ρL/A where ρ ie. rho, is the resistivity of the material. Note that ρ is a characteristic of the specific material and may vary with temperature. Hint 3) Ohm's law tells us that the potential difference V between the ends of a conductor is equal to the product of the current I through the conductor and the conductor's resistance R, V=IR
