What is the dimension and SI unit of permittivity?
In electromagnetism, the absolute permittivity, often simply called permittivity and denoted by the Greek letter ε (epsilon), is a measure of the electric polarizability of a dielectric. The SI unit for permittivity is farad per meter (F/m).
What are the dimensions of the electrical permittivity?
Electric Permittivity
