Question

A…….. (lot of charged particles / potential difference) needs to be created for electric current to flow.

Answer 1

1. The electrical potential difference is characterized as the amount of work performed in an electrical field to bring a unit charge from one point to another.
2. A short term for the electrical force that will push an electrical current between such points is the potential difference between two points.
3. To make flow of charge we need some external force in a particular direction.
4. This force is provided by potential difference.
5. No current will flow if there is no potential difference between two terminals even though a lot of charged particles are created.

Hence, A……potential difference.. (lot of charged particles / potential difference) needs to be created for electric current to flow.
