WebPotential difference equation and symbol. Another set of equations which deal with potential difference are those defined in Ohm's law, which describe how the current \(I\) passing through an Ohmic electrical component is determined by the potential difference \(V\) across the component and the component's electrical resistance \(R\). WebIn electrochemistry, the Galvani potential (also called Galvani potential difference, or inner potential difference, Δφ, delta phi) is the electric potential difference between two points in the bulk of two phases. These phases can be two different solids (e.g., two metals joined together), or a solid and a liquid (e.g., a metal electrode submerged in an electrolyte). simply boho classroom decor
