Electric Potential is the work done per unit charge in order to bring the charge from infinity to a point in electric field while Electric potential difference is the Potential developed while moving a charge from one point to another in the field itself.

Answer 2

Answer:

Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field

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

An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume

trying to stop something from happening or to stop somebody from doing something; fighting back against somebody/something

Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). ... Conductors: Materials that offer very little resistance where electrons can move easily. Examples: silver, copper, gold and aluminum.
