How to Evaluate Cell Potential?

Cell Potential evaluator uses Cell Potential in Potentiometry = Indicator EMF-Reference EMF+Junction EMF to evaluate the Cell Potential in Potentiometry, The Cell Potential formula is defined as one of the important concepts that help us understand the process of electromagnetism. The electromotive force is abbreviated as the EMF and it is closely associated with the more common concept of voltage. The electromotive force is the total energy provided by a battery or a cell per coulomb q of charge crossing through it. Cell Potential in Potentiometry is denoted by E_cell symbol.

How to evaluate Cell Potential using this online evaluator? To use this online evaluator for Cell Potential, enter Indicator EMF (Ei), Reference EMF (Er) & Junction EMF (Ej) and hit the calculate button.
