How to Evaluate Indicator EMF?

Indicator EMF evaluator uses Indicator EMF = Reference EMF-Junction EMF+Cell Potential in Potentiometry to evaluate the Indicator EMF, The Indicator EMF 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. Indicator EMF is denoted by Ei symbol.

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