Question

How does area and length of a wire effects Specific Resistance?

Answer 1

Like the resistance to water flow, the total amount of resistance to charge flow within awire of an electric circuit is affected by some clearly identifiable variables. First, the totallength of the wires will affect the amount ofresistance. ... Wider wires have a greater cross-sectional area.

Answer 2

Graphics to illustrate how resistance varies with l, A and rho. ... its length– the longer the wire, the greater its resistance. its cross-sectional area A – the greater the area, the less its resistance. the resistivity of the material r – the greater the resistivity, the greater its resistance.
