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). WebWe use a voltmeter to measure potential difference (or voltage). Potential Difference formula:** V = I x R** The potential difference (which is the same as voltage) is equal to the amount of current multiplied by the resistance.
