How to Calculate Reference EMF?
Reference EMF calculator uses Reference EMF = Indicator EMF+Junction EMF-Cell Potential in Potentiometry to calculate the Reference EMF, The Reference 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. Reference EMF is denoted by Er symbol.
How to calculate Reference EMF using this online calculator? To use this online calculator for Reference EMF, enter Indicator EMF (Ei), Junction EMF (Ej) & Cell Potential in Potentiometry (E_{cell}) and hit the calculate button. Here is how the Reference EMF calculation can be explained with given input values -> -5 = 5+10-20.
