Abstract. A voltage source is modeled by a semiclassical perturbation of the quantum momentum operator. Applying the quantum formalism we obtain a formula for the electric current in a 1-dimensional piece of metal. It turns out that for the model based dependence between voltage and current Ohm's law is valid for a realistic range of voltages.
