Mobility derivation class 12

WebOn substituting equation (2) and (3) in equation (1) we get, Mobility = Drift velocity × [Electric Field] -1. Or, M = [M 0 L 1 T -1] × [M 1 L 1 T -3 I -1] -1 = [M -1 L 0 T 2 I 1 ]. Therefore, … WebThe differential form of this law can be expressed through the following equation: q = -k.∇T Where ∇T refers to the temperature gradient, q denotes the thermal flux or heat flux, and k refers to the thermal conductivity of the material in question.
