Answer: Volts is the unit used to measure cell potential.
Step-by-step 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...
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.
