Question

18) What is electric potential difference? Give the unit of electric potential.​

Answer 1

Answer:

Answer ⤵️

Units of potential difference are joules per coulomb, given the name volt (V) after Alessandro Volta. The familiar term voltage is the common name for electric potential difference. Keep in mind that whenever a voltage is quoted, it is understood to be the potential difference between two points.

Answer 2

Answer:

Voltage, electric potential difference, electric pressure or electric tension is the difference in electric potential between two points, which is defined as the work needed per unit of charge to move a test charge between the two points.

The SI unit of electric potential is the volt, which is defined as a joule per coulomb.
