WebThe electron mobility, μ, relates the velocity of charged particles in a uniform electric field ( μ = v / E). When these equations are combined, we find: σ = n × e × v / E. The numerator is in units of charge per area per unit time (or current density, J), so J = n × e × v, and the denominator is electric field, E. Re-arranging and ...
WebCurrent has the SI base unit of Amperes so this cannot be reduced any further. R = VA -1. Voltage = Joules per Coulomb of charge. V = JC -1. Joules and Coulombs are derived so need to be broken down further. Q = It = Ampere seconds = As.
