The electrical potential of a point is a value that is related to how much potential energy a charged particle at that position has, based on the electric field around it (it is however not the same as the potential energy).
Electric fields are conserved force fields. What this means is that, if you go from one place to another, it does not matter which way oyu take, the energy it takes depends only on the start and end positions. This also applies to the potential (in fact, the potential wouldn't exist if it wouldn't).
So to find the difference in potential, you just subtract the potential at one point from the potential at the other point.
This simple subtraction is only possible because the potential is conservative. If you travel from your house to the supermarket, the energy it takes you very much depends on which road you choose. Because of that, you can't say what the energy difference (related to potential) is between your house and the supermarket without specifying how you travel.

What is the difference between electrical potential and electromotive force?
electric potential is potential difference between two points in closed circuit. but electromotive force is potential difference in any open circuit.
What does voltage mean in science?
It is defined as electromotive force, and the difference in electrical potential between 2 points in a circuit. It has also been explained as the pressure in an electrical circuit.
What does pd stand for in physics?
Pd in the periodic table stands for palladium.
What instrument do you use to measure electrical force?
Electric force is the attractive or repulsive force between two charged particles. The potential difference between two points can be measured with a Voltmeter.
Will there be a current between the two points if the electrical potential energy at one point in a circuit is greater than the electrical potential energy at another point?
Yes.
Uses of voltmeter?
A voltmeter is used to measure the difference in electric potential ("voltage") between two points, usually but not necessarily in an electrical circuit..

What is used to measure the difference in electrical potential between two points in a circuit.?
voltmeter
A is used to measure the difference in electrical potential between two points in a circuit?
voltmeter
What is used to measure the difference in electrical potential between two points in a circuit?
voltmeter
Why voltage is measured between 2 points?
because voltage is the 'electrical potential difference'. since a "difference" can only be evaluated between two points so is voltage :)
What you measure voltage into?
You measure voltage using a voltmeter which involves measuring the electrical potential difference between 2 points in an electrical circuit.
Why it is incorrect to say the voltage at point x is 12volts?
Voltage is the electrical potential difference between two points.
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.
