Answer: Volts is the unit used to measure cell potential.
Explanation:
Units is defined as the standard which is used to make comparisons between the measurements.
For Example: Meter is the unit used to measure length, Liters is the unit used to measure volume etc...
[tex]E_{cell}[/tex] is defined as the EMF of the cell. It is the energy provided by a cell per coulomb of charge that passes through it. It is measured with the unit of Volts (V).
Hence, volts is the unit used to measure cell potential.
