What is the SI Unit of Electric Flux?

The SI unit of electric flux is the volt meter (V·m or Vm). Electric flux is a measure of the electric field passing through a given area. It quantifies the flow of electric field lines through a surface, indicating the strength of the electric field penetrating that surface.

Mathematically, electric flux (Φ) is defined as the dot product of the electric field vector (E) and the area vector (A).

The volt meter (V·m) as the SI unit of electric flux is derived from the fundamental units of electric field (volts per meter, V/m) and area (square meters, m²). Thus, electric flux represents the electric field intensity (in volts per meter) integrated over an area (in square meters), resulting in the unit V·m.
