Question

It is important to remember that one can associate a putenla function only with a conservative force. cal e nergy In an electric field, the force is given by the expression FE. T Equations 1 and 2, one can then obtain expressions for the work dos the electric field on a charge q, and the resulting potential energyof th charge. In dealing with electric fields, it is convenient to define the electi potential difference AV as the change in electrical potential energy U per unit charge between two points A and B, or by ric Eq. 3) You can think of the electric potential difference as the work per unit charge that an external agent must perform to move a test charge from point A to B. The electric potential difference is also known as the voltage difference. Explain the difference between electrical potential energy and electric potential difference. Batteries always have two terminals, labeled + and -. The + terminal has the higher electric potential. If you connected the terminals to a circuit, which way would positive charges flow in the circuit? What about negative charges?

Explanation / Answer

First Part –

Electric potential energy is defined as the energy that charged particles (any charge q) have because of its own electric charge and its relative position to the other charged particles.

Whereas electric potential difference is defined as the work per unit charge that an external agent must perform to move a test charge from two points A and B.

Second Part –

When we connect the terminals to a circuit, positive charges from the positive terminal start to flow towards the negative terminal. As a result of this current flows.

The flow of positive charge also result the flow of negative charges. But the direction of flow of the negative charge is opposite to the direction of flow of the positive charges.
