What is sigma in physics electric field?
Understand the Problem
The question is asking for the meaning of 'sigma' in the context of electric fields in physics. Typically, 'sigma' could refer to surface charge density or a parameter related to the field equations.
Answer
Surface charge density.
In physics, σ (sigma) refers to surface charge density, which is the amount of charge per unit area on a surface, measured in coulombs per square meter (C/m²).
