Example of Contour Integral
Let $\mathbf E$ be an electric field acting over a region of space $R$.
Let $OA$ be a contour in $R$.
Let $\d \mathbf l$ be a small element of length of $OA$ at a point $P$.
Then the potential difference between $O$ to $A$ is given by the contour integral:
- $\ds \int_O^A \mathbf E \cdot \d \mathbf l$
