WebAnalysis of Results. The resistivity, ρ, of the wire is equal to Where: ρ = resistivity (Ω m); R = resistance (Ω) A = cross-sectional area of the wire (m 2); L = length of wire (m); Rearranging for the resistance, R, gives: Comparing this to the equation of a straight line: y = mx WebThe rate at which the electrons flow in a circuit is measured in amperes (A). One ampere of current is approximately equivalent to 6.24×10^18 electrons moving past a boundary in one second. The amount of charge (Q) is determined by a steady current (I) flowing in the circuit for a time (t). Q=I×t.
