Difference between cell potential and emf
WebApr 6, 2024 · Now we will understand what EMF is in Physics and what is meant by EMF in Physics. So, the Electromotive Force is the maximum potential difference between two electrodes of the cell when no current is drawn from the cell. The Electromotive Force is denoted by E or sometimes it is also denoted by the symbol ε. WebNov 17, 2024 · V is the terminal voltage; emf is the maximum potential difference delivered by a cell or a generator when there is no current flowing through it, r is the internal resistance, whereas I is the current that flows at the time of the measurement. If the current is flowing away from the positive terminal, I is positive.
