Gauss's Law

Gauss's Law

### Formula

$$\oint\vec E\cdot d\vec A=\frac{q_{enclosed}}{\epsilon_0}$$

### Terminologies

- qenclosed → Charge enclosed by Gaussian surface.

- ε₀ → Permittivity of free space.

### Conditions / Special Cases

Applicable for:

- Spherical symmetry.

- Cylindrical symmetry.

- Planar symmetry.

### Usage

- Used to calculate electric fields easily.
