Describe the potential difference in conductors

1-

If a distribution of charge is created on a conductor in such a way that a potential difference exists between two points on the conductor, an electric between two points on the conductor, an electric field exists in that region. This field tends to cause a flow of positive charge in the direction of the field or flow or negative charge in the direction of the field or a flow of negative charge in the opposite direction. Work is done the charge in the field as the flow takes place. In the case of an isolated conductor the work is done at the original charge distribution; when the portal difference across the conductor is removed by the flow of charge, the field disappears and the flow ceases.

Let us suppose that a constant potential difference two points on a conductor can be maintained in spite of the resulting flow of charge. Then the flow of charge will continue between the points at a consent rate. A time rate of flow of charge is called an electric current. Such currents constitute one of the most widely used means of transmitting energy in the modern world. In order to maintain energy in the potential difference and currant, charge must be potential and removed from the place of lower potential and removed from the place of lower potential along some path other than that taken by the current already mentioned. Energy must also be supplied by some outside agency to affect the transfer of charge and to maintain the potential difference. Charge and to maintain the potential difference. Hence, in order to maintain a constant current, a complete conducting loop, or converting some other form of energy to electric energy.
