Answer 1

Answer:

Electric potential is the amount of energy per unit charge at a particular point. When a coulomb charge at any point possesses large potential energy then the point has large electric potential. Similarly, if a coulomb charge at a point possesses small potential energy then that point has lower electric potential. The difference in the electric potential between the two points is called the electrical potential difference.

 

Electric potential difference can also be called the voltage. In a static electric field, electric potential difference or voltage is defined as the amount of work done to move a test charge from one point to another. So, What is the SI unit of 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.
