In a uniform electric field, the equation to calculate the electric potential difference is super easy: V = Ed. In this equation, V is the potential difference in volts, E is the electric field strength (in newtons per coulomb), and d is the distance between the two points (in meters).

The electric potential difference between points A and B, VB − VA, is defined to be the change in potential energy of a charge q moved from A to B, divided by the charge. Units of potential difference are joules per coulomb, given the name volt (V) after Alessandro Volta. 1V = 1J/C

The standard metric unit on electric potential difference is the volt, abbreviated V and named in honor of Alessandro Volta. One Volt is equivalent to one Joule per Coulomb. If the electric potential difference between two locations is 1 volt, then one Coulomb of charge will gain 1 joule of potential energy when moved between those two locations.

The terms electric potential and electric field are useful in physical chemistry, under the subcategory of electrochemistry. The key difference between electric potential and electric field is that electric potential refers to the work need to be done in order to move a unit charge from one place to another, under the influence of an electric field whereas electric field is the surrounding of an electrical charge which can exert a force on other charges in the field. Reference: 1.

The potential difference is expressed in volt (V). The potential difference between two points is said to be 1 volt if the work is done in moving 1-coulomb charge from one point to other is 1 joule. 1 volt= 1 joule/ 1 coulomb Unit for measuring the potential difference is volt and instrument used for measuring potential difference is a voltmeter.

We define a new term, the electric potential difference (removing the word "energy") to be the normalized change of electric potential energy. Electric potential difference is the change of potential energy experienced by a test charge that has a value of. Electric potential energy difference has units of joules.

If the electric field is constant, then the change in electric potential from one foot to the other is the product of the electric field and the distance between the feet.

We are given the maximum electric field E between the plates and the distance d between them. The equation V AB = Ed can thus be used to calculate the maximum voltage. Solution. The potential difference or voltage between the plates is. V AB = Ed. Entering the given values for E and d gives. V AB = (3.0 × 10 6 V/m)(0.025 m) 7.5 × 10 4 V or V AB = 75 kV.
