Question:
What affects the resistance of a wire? and also could you explain what causes the wire to resist the flow of the current?


Replies:
Conduction electrons moving through the wire bang into electrons attached to atoms. This converts some of the electrical energy to heat.

Tim Mooney


The itt effect the resistance in wires:

Length
Cross sectional area
Material
Temperature

What causes the wire to resist the flow of current are impurities in the wire and imperfect atomic alignments.
