Gauss's Law Calculator

Find the electric flux through a surface enclosing a charge.

Calculated Output

Electric flux (V·m) 112,940.91

Formula: Φ = Q ÷ ε₀

Step-by-Step Breakdown

1. Values used:

2. Enclosed charge = 0 C

4. Electric flux = 112,940.91V·m

Did this calculator solve your problem today?

The math behind it

Φ = Q_enclosed ÷ ε₀, where ε₀ is the vacuum permittivity. The shape of the surface doesn't matter.

1 µC enclosed → flux ≈ 1.13 × 10⁵ V·m.

Does external charge contribute?

No — only charge inside the closed surface affects the net flux.
