WebFeb 18, 2024 · If the original length of the wire is l and its cross-sectional area is A, then its resistance, R=ρl/A. When the length becomes 2l, cross-sectional area reduces to A/2 because volume of the wire does not change. Changes resistance, R′=ρ (2l) (A/2)=4ρlA=4R. WebWhen the length of the wire is increased then the resistance will also increase as the electrons will have a longer distance to travel and so more collisions will occur. Due to this the length increase should be proportional to the resistance increase.

WebWhen electrons start to move, they get scattered from the nuclei present in the material which is the wire made from. This process creates the resistance. Thus, when the length … WebAs the length of the wire increase so does the atoms in the wire, this will therefore increase the resistance, as there will be more atoms for the flow of elections to pass through. … orcieres webcam

WebNov 20, 2024 · The thicker the wire, the lower the resistance. (3) Material: the material the wire is made out of will affect the resistance. Different materials have different resistivities, which is the ability of the material to allow electrons to move. It is dependent on electronic structure and temperature. Webhow does the thickness of a wire affect the resistance - Example The absolute threshold is a concept in psychology that refers to the minimum amount of a stimulus that an individual can detect.
