Answer:
The current flow occurs due to the difference in electrical potential
Step-by-step explanation:
The difference in electrical potential between two point in electrical circuit causes charges to flow, usually from the region of higher potential to the region of lower potential. The flow of these charges is known as current.
Thus, the current flow occurs due to the difference in electrical potential. Electric potential means work done in moving a unit positive charge from infinity to a particular point in the field against the electrical resistance of that field.
