Electric potential is a measure of the amount of work needed to move a unit of positive charge from one point to another against an electric field.
Electric potential is calculated by dividing the electric potential energy by the charge of the object. It is measured in volts (V).
Negative electric potential represents an area of high potential energy, while positive electric potential represents an area of low potential energy.
The midpoint between a negative and positive charge is considered a point of zero electric potential because the electric fields from the positive and negative charges cancel each other out at that point, resulting in no net electric potential.
As distance increases, the electric potential decreases. This is because the electric field strength decreases as distance increases, resulting in less work needed to move a charge and a lower electric potential.
