What does an electric circuit mean? Name a device that helps to maintain a potential difference across a conductor in a circuit.When do we say that the potential difference across a conductor is 1 volt? How much work is done in moving a charge of 3C across two points having a potential difference of 14V?

Answer:
An electric circuit includes a device that gives energy to the charged particles constituting the current, such as a battery or a generator; devices that use current, such as lamps, electric motors, or computers; and the connecting wires or transmission lines.
Any source of electricity like battery, cell, power supply, etc. helps to maintain a potential difference across a conductor.
Potential Difference across a conductor is said to be 1 volt if 1 Joule of work is done in bringing 1 Coulomb from one point to another in a conductor.
The potential difference(p.d) between two point in an electric circuit is defined as the amount of work done in moving a unit charge from one point to the other point. Hence, the work done in moving the charge is 45 J
