Electric potential and potential difference are two different things. The **main difference between electric potential and potential difference** is that electric potential is defined at a point whereas the potential difference is defined between two points.

Let see in detail the differences based upon definition, formula, unit, etc.

## Difference between Electric Potential and Potential Difference in tabular form

Electric Potential |
Potential Difference |

The electric potential at a point (P) in an electric field is defined as the work done per unit charge in moving a unit positive charge from infinity to that point (P), irrespective of the path followed. | The potential difference between two points in an electric field is defined as the work done per unit charge in moving a unit positive charge from one point to another point, irrespective of the path followed. |

It is defined at a point. | It is defined between two points. |

The electric potential at a point P is given by
$V_P=\frac{W_{\infty P}}{q_o}$ where W |
The potential difference between point P and R is given by
$V_{PR}=V_P – V_R=\frac{W_{RP}}{q_o}$ where W |

The SI unit of electric potential is volt (V). |
The SI unit of potential difference is also volt (V). |

In c.g.s. system, unit of electric potential is stat volt. |
In c.g.s. system, unit of potential difference is also stat volt. |

It is a scalar quantity. | It is also a scalar quantity. |

The electric potential at infinity is taken as zero. | There is no such concept. |

## Conclusion

The key difference between the electric potential and potential difference is that electric potential is calculated at a point whereas the potential difference is calculated between two different points.
