SUMMARY
The average electric field over a spherical surface is calculated using the integral formula \(\frac{1}{4\pi R^2}\oint\mathbf{E}\cdot d\mathbf{a}\). This formula results in a scalar value rather than a vector, which is a crucial distinction in understanding electric fields. The discussion references a previous thread on Physics Forums that addresses similar questions, providing additional context and insights into the topic.
