==Key Stage 5==
===Meaning===
'''Electric potential''' at a point in an [[Electric Field|electric field]] is the [[Work Done|work done]] per unit [[Electrical Charge|charge]] to move a small positive test [[Electrical Charge|charge]] from infinity to that point.

===About Electric Potential===
*'''Electric potential''' is denoted by the symbol '''𝑉'''.
*'''Electric potential''' is [[measure]]d in volts (V).
*The [[Potential Difference|electric potential difference]] (pd) between two points is the [[Work Done|work done]] to move a unit [[Electrical Charge|charge]] between those points.
*[[Equipotential]] surfaces are surfaces on which the '''electric potential''' is the same; no [[Work Done|work]] is required to move a [[Electrical Charge|charge]] along an [[equipotential]] surface.

===Formula===
'''Electric potential''' is given by the general formula:
*<math>𝑉=\frac{𝑊}{𝑄}</math>
Where:
*𝑉 is the '''electric potential'''
*𝑊 is the [[Work Done|work done]]
*𝑄 is the [[Electrical Charge|charge]]
The '''electric potential''' due to a point [[Electrical Charge|charge]] is

*<math>𝑉=𝑘\frac{𝑄}{𝑟}</math>

Where:
*𝑘 is the Coulomb's constant,
*𝑄 is the charge, and
*𝑟 is the distance from the [[Electrical Charge|charge]].

 *<math>𝑉=𝑘\frac{𝑄}{𝑟}</math>
 Where:
-*𝑘 is the Coulomb's constant,
+*𝑘 is the [[Coulomb's Constant|Coulomb's constant]]
-*𝑄 is the charge, and
+*𝑄 is the [[Point Charge|point charge]] causing the field
-*𝑟 is the distance from the [[Electrical Charge|charge]].
+*𝑟 is the distance from that [[Point Charge|point charge]]
