## Study Notes

### Integral Form of Gauss's Law

- States that the electric flux through a closed surface is proportional to the charge enclosed within that surface.
- Mathematically represented as ∮ E ⋅ dA = Q_enc/ε₀, where E is the electric field, dA is the differential area vector, Q_enc is the enclosed charge, and ε₀ is the electric permittivity of free space.

### Gauss's Law for Electric Field

- Describes the relationship between electric charge distribution and the resulting electric field.
- It is particularly useful for calculating electric fields for symmetrical charge distributions.

### Positive Electric Charge Convention

- According to convention, a positive electric charge generates an outward electric field.
- Electric field lines emanate from positive charges and terminate on negative charges, indicating the direction of force on a positive test charge.

### Publication of Gauss's Law

- Gauss's law for the electric field was published in 1835.
- Named after mathematician and physicist Carl Friedrich Gauss, who contributed significantly to the field of electrostatics.

### Electric Permittivity of Free Space

- Denoted as ε₀ in Gauss's law.
- Represents the capability of a vacuum to permit electric field lines and is a fundamental constant in electromagnetism, with a value of approximately 8.85 x 10⁻¹² F/m.
