The unit of measurement for electric potential is the volt, represented by the letter ‘V‘.
Electric potential, often referred to as voltage, is a measure of the potential energy per unit charge available to move electric charge from one point to another in an electric field. One volt is defined as the potential difference that would move one joule of energy per one coulomb of charge. Hence, in the options provided:
- a) joules (j) – This measures energy.
- b) newtons (n) – This measures force.
- c) volts (v) – This is the correct unit for electric potential.
- d) moles (m) – This measures the amount of substance.
- e) electronvolts (ev) – This is a unit of energy specifically for atomic and particle physics.
- f) joule-coulombs (jc) – This is not a standard unit for electric potential.
Therefore, the correct answer is option c) V.
