The unit of potential difference in a circuit is the volt.
Electrical charge is measured in coulombs (1 coulomb = 6.241x1018 e, electron charges) and a volt is equal to 1 newton per coulomb at a distance of 1 meter.

What unit would be used to measure the potential difference between two poles of a battery?
The volt.The volt.The volt.The volt.
What is voltage what is another name for votage?
What is voltage what is another name for voltage? That is potential difference. In physics, the potential difference or p.d. between two points is the amount of work that would need to be done on a unit electric charge to move it from one point to the other against an electric field. P.d. is synonymous with voltage and is measured in volts. http://en.wikipedia.org/wiki/Potential_difference http://en.wikipedia.org/wiki/Voltage Cheers ebs
What is the difference between scheme of work and unit plan?
There is no difference between a unit plan and a scheme of wok. thank u. By highkult
The unit of electric potential difference between two points is?
You can compare 'potential' with height, and 'potential difference' with the difference in height.The height of an object depends upon from where you measure it. For example an object three-quarters of the way up a 1000 m mountain is +750 m from the base of the mountain, but -250 m from the top of the mountain. Note how we apply a positive or a negative sign to indicate whether we are measuring upwards or downwards.The same applies to potential. It's value depends upon from where it is measured. For example, two charged objects could have a potential of , say, +5 V with respect to earth (ground) and a potential of -15 V with respect to earth. But the potential difference between them will be +5 - (-15) = 20 V.Notice how, in the above example, we always show a positive or negative sign when we talk about potential, but we don't use these signs when we talk about a potential difference. Furthermore, it is important that we must ALWAYS specify the reference point when we describe potential -e.g. "What is the potential at point A, with respect to (say) earth?"Taking this further. It's important to know that the term 'voltage' means 'potential difference', and not'potential'! It would be quite wrong to say that the 'voltage of an object is (say) -200 V with respect to earth'. The correct expression would be the 'potential of an object is -200 V with respect to earth'.
What is used to pontential difference?
The amount of energy per unit charge needed to move a charged particle from a reference point to a designated point in a static electric field.
What is a voltage of a battery?
It is the potential difference between the positive and negative terminals of the battery. The unit of electrical potential is the volt, so the difference in potential between two ponts is also a quantity with units of volts, colloquially called the 'voltage' between the points.
What does pd stand for in physics?
Pd in the periodic table stands for palladium.
What unit shows the difference in charge between two points?
I don't think such a unit is used, or would make much sense, in physics. That sounds like the description of voltage - unit volt. However, the volt is not really a difference in electric charge, but rather, of electric potential. It can be understood as potential energy related to electric fields: if there is an electric potential between two points, it requires a certain amount of energy to move a unit charge from one point to the other. Thus, the unit volt is equivalent to joules / coulomb.
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 the unit of measure that expresses potential different between two electrodes in a battery?
Volt
What is the unit of potential difference?
The unit for electric potential difference is the volt (V).
What is voltage difference?
Voltage at a point is defined as the work done by a unit positive charge carrying it from infinity to that point. while volage diffrance between two points is the work done bye unit positive charge from one point to the other point.work may be positive or negative depend upon the nature of charge that's why the potential will be negative or positive .CommentBy definition, voltage means potential difference. For this reason, you cannot have 'a voltage at a point' because potential difference, or voltage, exists between two points. You can, however, have a potential at a point.
What is the electrical unit of potential difference?
Potential Difference is measured in Volts
What is a unit of measure that expresses potential difference between two electrodes in a battery?
Volt
What is the ohm?
The Ohm is a unit of measure of resistance to the flow of electricity. The ohm is defined as a resistance between two points of a conductor when a constant potential difference of 1 volt, applied to these points, produces in the conductor a current of 1 ampere.
What is the unit of measure that expresses potential difference between the two electrodes in a battery?
Volt
What is the difference in energy per unit of charge between two points in a circuit?
voltage
