What is ohmic diffusion?

Ohmic diffusion refers to the process in which charged particles or ions move through a medium under the influence of an electric field, leading to a redistribution of charge. This phenomenon occurs in electrolytes and semiconductors where the movement is driven by the concentration gradient and electric potential. It is characterized by a linear relationship between the current density and the electric field, consistent with Ohm's law. Overall, ohmic diffusion plays a crucial role in various electrochemical processes and applications.
