Voltage is (potential energy). Energy is the amount of work that the electrical current can perform... total watts. Voltage is just a potential. An electric spark can jump a distance through air, and the distance is determined by voltage. A full description would take quite a bit of time and space on this web site, but some physics or other science books can certainly give an adequate description of the relationship between Volts, Amps and Watts, and give meaning to the formula: Volts X Amps = Watts

∙ 14y agoVoltage can be likened to pressure applied to water in a pipe. The pipe is similar to a conductor (i.e., a wire) in electronics. The amount of water that flows (i.e., gallons per minute) in response to pressure applied is similar to the amount of electrical current that flows through a conductor in response to the electrical "pressure" that is applied. By connecting a battery (or other source of electrical power) to a loop of circuitry (like the loop of Plumbing in the walls of a building) one end of the loop is made electrically more "positive" than the other. This difference between the positive and negative is the "pressure" that is applied. For a given loop of circuitry, the more voltage is applied (hence the more "pressure") the more electrical current will flow (measured in amperes -- similar to "gallons per minute" in plumbing).

What is mean by a potential difference?
Another name for potential difference is voltage.
What does not provide a voltage a difference in a circuit?
Wires do not provide a voltage differenceAnswerAs 'voltage' is synonymous with 'potential difference', you appear to be asking "What does not provide a potential difference difference in a circuit?", which does not make any sense!
What difference's between potential transformer and voltage transformer?
Both are same. This is an instrument transformer used for metering & protections.
What is the difference between a voltage converter and a voltage regulator?
the difference between a voltage converter to a voltage regulator,is that a voltage converter,converts or changing the desired voltage to be used while the voltage regulator,regulates the input of the voltage amount not to excess to its inputs.
Current is proportional to the potential difference and inversely proportional to its?
Current is proportional to the potential difference and inversely proportional to resistance. Ohm's law: Current equals voltage divided by resistance
How can you get the largest voltage difference?
There is no such thing as a 'voltage difference'! 'Voltage' means 'potential difference', so what you appear to be asking is "How do you get the largest potential difference difference?'! Potential difference is caused by the separation of charges between two points. The greater the amount of charge separation, the greater the potential difference.
What are the differences between voltage and potential difference?
Voltage is the potential difference to the ground. By convention, ground potential is zero volt.The above answer is incorrect. 'Voltage', by definition, is potential difference. It has nothing to do with being measured with respect to ground -in fact potential difference (voltage) cannot be measured with respect to anything.
Define the 'potential difference between the ends of a conductor'?
The potential difference between the ends of a conductor is called voltage.
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.
Difference between voltage and emf?
'Voltage' is simply another term for 'potential difference', and an electromotive force is the open-circuit, or no-load, potential difference of a source such as a battery or generator.
What is the potential difference measured in volts?
'Force' isn't measured in volts. Potential and potential difference are measured in volts.
What is the importance of voltage?
importance of voltage is the potential difference between two points.
What is potential difference or voltage?
If you take two different nodes in a network and if you find the difference in voltage for those nodes then it is known as potential or voltage difference. Here the reference is not taken. But if you find potential difference between a node and its respective ground it is known as voltage at that node here reference is ground potential i.e zero.Answer'Voltage' is synonymous with 'potential difference'; they both mean the same thing. And it is important that these terms are not confused with 'potential'. So, it is incorrect to say 'voltage difference' (which would mean 'potential difference difference'!), or to describe a voltage as existing 'at' a particular point, or 'with reference to', for example, earth or ground.In very simple terms, if two points are at different potentials, then there is a potential difference (or 'voltage') between them. A potential exists when work is done moving a charge to a particular point; the greater the work, the higher the potential. 'Potential' is roughly equivalent to the potential energy gained by an object when it is lifted against the force of gravity.Think of it this way: 'potential' is equivalent to 'height', whereas 'potential difference' (voltage) is equivalent to the difference between points at different heights.
What does a battery create between terminals?
Potential difference (voltage)
What is the difference between voltage divider and potential divider?
its the same
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 :)
Are potential difference and voltage always the same?
Voltage is simply another word for potential difference.
