GEOLOGY

Detailed explanation-1: -Electric potential energy exists if there is a charged object at the location. Electric potential difference, also known as voltage, is the external work needed to bring a charge from one location to another location in an electric field.

Detailed explanation-2: -The electric potential, or voltage, is the difference in potential energy per unit charge between two locations in an electric field.

Detailed explanation-3: -The greater the voltage, the greater the electric field in a circuit and the greater the electric potential energy per charge transformed as charges move in the circuit.

Detailed explanation-4: -Electric Potential Formula: If two like charges (two protons or two electrons) are brought towards each other, the potential energy of the system increases. If two unlike charges i.e. a proton and an electron are brought towards each other, the electric potential energy of the system decreases.

Detailed explanation-5: -Potential difference between two points is equal to work done / charge.
