<p><b>New page</b></p><div>'''Electric potential''' is a fundamental concept in [[physics]] and [[electromagnetism]], defined as the amount of [[electric potential energy]] that a [[electric charge|charged particle]] would have if located at a specific point in space. It is also known as the ''electric potential difference'' and is measured in [[volt]]s.<br />
<br />
== Definition ==<br />
The electric potential at a point in space is defined as the work done by an external agent in carrying a unit positive charge from a reference point to that point without any acceleration. It is important to note that the reference point is usually taken at infinity.<br />
<br />
== Mathematical Representation ==<br />
The electric potential ''V'' at a point ''r'' in a static electric field ''E'' is given by the line integral:<br />
<br />
:''V = - ∫ E • dl''<br />
<br />
where ''dl'' is an infinitesimal element of the path.<br />
<br />
== Relation with Electric Field ==<br />
The electric potential is related to the electric field by the equation:<br />
<br />
:''E = - ∇V''<br />
<br />
where ''∇V'' is the gradient of the electric potential.<br />
<br />
== Applications ==<br />
Electric potential has numerous applications in various fields such as [[electronics]], [[electrical engineering]], and [[physics]]. It is used in the design of [[electric circuits]], [[capacitors]], and [[batteries]]. It also plays a crucial role in understanding phenomena like [[electric discharge]], [[electric shock]], and [[electric current]].<br />
