Potential Difference


The potential difference between two points in an electrical circuit is the electrical energy converted into other forms of energy per unit charge passing from one point to the other.

$V = \frac{W}{Q}$

, where

  • V is electric potential difference,
  • W is work done/ energy,
  • Q is charge

One volt is the potential difference between two points in an electrical circuit when one joule of electrical energy is converted to other form of energy as one coulomb of charge passes from one point to the other.
