Sigma physics electric field
WebMicroscopically, Ohm's law is a statement about how application of an electric field to a conducting material leads to an electric current: \vec {J} = \sigma \vec {E}. J = σE. In the above equation, \sigma σ is a constant called the conductivity of a material, \vec {E} E is the applied electric field, and \vec {J} J is the electric current ...
