Here are two of the most common examples: Apparent power (VA) = 1.732 x Volts x Amps. In other words the potential difference is defined as the difference in the electric potential of the two charged bodies. Electric Potential & Potential Difference Definition: The electrical potential is defined as the capability of the charged body to do work. When there is potential difference between any two points, current starts flowing from high pressure point to low pressure . Electric potential difference is a measure of the amount of potential energy at a given location in a circuit. The potential difference between two points is measured by voltmeter. The current in a circuit is directly proportional to the electric potential difference impressed across its ends and inversely proportional to the total resistance offered by the external circuit. It is the amount of work done in moving a unit charge from one point to another point. Units of potential difference are joules per coulomb, given the name volt (V) after Alessandro Volta. One of the most important applications of electric potential is in the study of electric circuits. Relationship between Work, Charge and Voltage The unit of potential difference generated between two points is called the Volt and is generally defined as being the potential difference dropped across a fixed resistance of one ohm with a current of one ampere flowing through it. You are using an out of date browser. For example, potential difference between A and B is found with following formula;VAB=VB-VA=-i.RThis formula shows the energy lost by charge moving from point A to point B.We should first find the direction of the current to determine values and i.R. Potential Difference = Work Done/Charge V = W/Q How is Potential Difference Measured? The potential difference between two points (1 and 2) of an electric field is equal to the work done by said field on the unit of positive charge to transport it from point 1 to point 2.
