What is 'electrical potential' - 'energy difference' or 'voltage'?

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'.

What does voltage cause the flow of?
there is a difference in electrical potential energy.
What is the difference in electrical potential energy between two places in a circuit?
Yes. I think that is a definition of current.
Does a voltage have one terminal?
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.
What is difference between voltage and emf?
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.
What is the difference between voltage ang current?
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'.
Define voltage in terms of electric potential energy and charge?
When unlike charges are moved farther apart, they gain electrical potential energy. Electrical potential difference is the change in potential energy per coulomb of charge. Voltage is the common name for electrical potential difference and is measured in volts (V). Electrical energy depends on the amount of charge and voltage. Electrochemical cells, or batteries, are a common source of voltage. We use voltmeters to measure potential difference. :)
What is the difference in electrical potential energy between two places in an electrical field?
voltage
Do charges in an electric circuit flow because of a difference in electrical potential energy?
"voltage" (also referred to as 'potential')
What does voltage cause the flow of?
there is a difference in electrical potential energy.
What generates electrical energy from chemical energy?
A battery stores chemical energy creating a voltage or potential difference that is the potential to do work.When a battery is connected to an electrical device, current flow and is so the conversion of chemical energy into electrical energy.
What is the voltage at the location of a 0.0001-Coulomb charge that has an electric potential energy of 0.5 joules?
Electric Potential = Electrical Potential Energy/ Charge The measurement for electric potential is call the volt. Electrical Potential is often called voltage. Voltage or Electrical Potential = 0.5 Joules / .0001 Coloumb = 5000
What is the difference in electrical potential energy between two places in a circuit?
Yes. I think that is a definition of current.
What are examples of electrical potential energy?
Any voltage source is a potential waiting for a load so that current can flow and "work" can be done. A battery and your power company that supplies your home are sources of electrical potential energy.
What is the difference between electrical potential energy and potential difference?
Electric potential is the electric potential energy per unit coulomb. So unit for electric potential is J/C and that of electric potential energy is simply J
What is voltage?
A type of "pressure" that drives electrical charges through a circuit. Voltage is how the electric potential energy differences are measured.
A battery has a difference in potential energy between the positive terminal and negative terminal which units express this difference in energy?
That's a difference in electrical potential, not potential energy.It's described in units of "volts".
What term for the difference in electrical energy between 2 places in a circuit?
Voltage.
