Electrical potential deals with moving a charge in a direction opposite to an electric field. So what we are actually dealing with is Potential Energy. This can be calculated by the equation of PE = QEd where Q is the charge of the particle, E is the electric field and d is the distance the charged particle has been moved. The units of all this ends up being Joules (J).

Now, electric potential difference is another story. This is the work per unit charge. In this case the unit will be V (volts).

AnswerYes.

'Voltage' is synonymous with 'potential difference', and must never be used to describe 'potential'.

So, for example, it would be correct to say that 'the voltage (or 'potential difference') between a line and a neutral conductor is 230 V'. Alternatively, we could say 'the potential of the line conductor is 230 V with respect to the neutral conductor'.

On the other hand, it would be totally incorrect to say 'the voltage of the line conductor is 230 V with respect to the neutral conductor', or 'the potential between the line conductor and the neutral conductor is 230 V'.

there is a difference in electrical potential energy.

Yes. I think that is a definition of current.

No. Voltage is the potential difference in energy between two charges. (Volts is joules per coulomb.) Since it is potential, that means it is relative, and in order to be relative, there must be two terminals.

An electromotive force (e.m.f.) is the open-circuit, or no-load, potential difference provided by a source -such as a battery or generator. For a closed circuit, an e.m.f. is the sum of the voltage-drops around any closed loop, including the internal voltage drop of the source.A potential difference (voltage) can exist across any circuit component. For example, the fact that current is flowing through each of several resistors in a series circuit means that there must be an individual potential difference across each of those resistors (which we also term 'voltage drop').An electromotive force is the name we give to the open-circuit potential difference provided by a generator, battery, etc. For example, the open circuit potential difference of a battery would be its electromotive force.So, if we use a series resistive circuit as an example, the battery would provide the electromotive force, while voltage drops would then appear across its internal resistance, and across each of the resistances. The magnitude of the electromotive force is then equal (but acting in the opposite sense) to the sum of the voltage drops, including the internal voltage drop.Many textbooks use the symbol, E, to represent an electromotive force, and V to represent potential difference. So, Kirchhoff's Voltage Law, for example, will often be seen written as: E = V1 + V2 + V3 + etc.

voltage: it is the potentail difference between two wires. or it is the amount of energy used to force the electrons.current: it is the flow of free electrons.by Balaji,NITCAnswerThere is no such expression as 'potential voltage'. 'Voltage' is simply another word for 'potential difference'.

Voltage is the electric potential energy per unit charge. It represents the potential difference between two points in an electric field, which determines the force that drives electric charges to move from one point to another. Voltage is measured in volts (V).

there is a difference in electrical potential energy.

Yes, charges in an electric circuit flow from areas of higher electrical potential energy to areas of lower electrical potential energy. This creates a potential difference that drives the flow of charges through the circuit.

Voltage. Voltage is the measure of the electric potential energy difference between two points in an electrical circuit. It is typically measured in volts.

Voltage is the energy per unit charge that is measured in volts. It represents the electrical potential difference between two points in a circuit.

A voltmeter is typically used to measure electrical potential energy. It is connected in parallel with the component or circuit being measured to determine the voltage difference or potential between two points.

Yes. I think that is a definition of current.

in an electric field due to the relative positions of charged objects. It is directly proportional to the amount of charge and the voltage difference between the objects. The formula for electrical potential energy is U = qV, where U is the energy, q is the charge, and V is the voltage.

The electrical energy measured by the voltmeter is produced by a power source, such as a battery or generator, that generates a voltage difference. This voltage difference creates an electric potential that drives the flow of electrons through a circuit, causing electrical energy to be transferred and measured by the voltmeter.

The voltage difference between two points in an electrical circuit is best described as electrical potential difference. This represents the energy per unit charge required to move a charge between those points.

Yes, there will be a current between the two points because a potential difference (voltage) exists between them. This potential difference will cause charges to flow from the higher potential energy point to the lower potential energy point, creating an electric current.
