What determines the emf of a cell?
The electromotive force of a cell or EMF of a cell is the maximum potential difference between two electrodes of a cell. It can also be defined as the net voltage between the oxidation and reduction half-reactions. The EMF of a cell is mainly used to determine whether an electrochemical cell is galvanic or not.

Solution. Thus, the emf of the cell at 25 ºC is 0.73 V.
What is EMF of a cell in physics?
The electromotive force (emf) is the sum of the electric potential differences produced by a separation of charges (electrons or ions) that can occur at each phase boundary (or interface) in the cell. The magnitude of each potential difference depends on the chemical nature of the two contacting phases.
What is EMF in simple words?

What is electromotive force in physics?
Electromotive force (EMF) is equal to the terminal potential difference when no current flows. EMF and terminal potential difference (V) are both measured in volts, however they are not the same thing. EMF (ϵ) is the amount of energy (E) provided by the battery to each coulomb of charge (Q) passing through.
What is the unit of EMF of a cell?
Like other measures of energy per charge, emf uses the SI unit volt, which is equivalent to a joule per coulomb.
