Your answer is Joule....!!!
Explanation:
The difference in the electric potential between the two points is called the electrical potential difference. ... The SI unit of voltage is volts and is represented by the letter v. One volt is defined as the energy consumption of one joule per electric charge of one coulomb.
In the International System of Units (SI), electric potential is expressed in units of joules per coulomb (i.e., volts), and differences in potential energy are measured with a voltmeter.
