Which of the following factors does not affect the the electric resistance of a wire?
Answer Details
The factor that does not affect the electric resistance of a wire is "mass". Mass is not a factor that determines the resistance of a wire. The resistance of a wire is dependent on its length, cross-sectional area, temperature, and the type of material it is made of.
The length of a wire is directly proportional to its resistance; the longer the wire, the higher the resistance. The cross-sectional area of a wire is inversely proportional to its resistance; the larger the area, the lower the resistance. The temperature of a wire affects its resistance because resistance increases with temperature for most materials. Finally, different materials have different resistance properties, and that affects the resistance of the wire.
