Definitions:

Potential Difference

The difference in electric potential between two points, which drives the flow of electric current in a circuit.

Conventional Theory

In electrical engineering, it refers to the theory that assumes current flows from the positive to the negative terminal, opposite to electron flow.

Electrical Current Flow

The movement of electric charge carriers, such as electrons, through a conductor or circuit, typically measured in amperes.
