## FAQ?

### What is the meaning of Epsilon 0 in physics?

For the ordinal number ε 0, see Epsilon numbers (mathematics). Vacuum permittivity, commonly denoted ε0 (pronounced as "epsilon nought" or "epsilon zero") is the value of the absolute dielectric permittivity of classical vacuum.

### What is the difference between permittivity and Epsilon?

It is often miss-used as the value of Epsilon not. Permittivity is the measure of the opposition offered against the formation of an electric field. The permittivity of free space ( ε0) is the capability of the classical vacuum to permit the electric field.

### What is the value of epsilon nought?

Vacuum permittivity, commonly denoted ε0 (pronounced as "epsilon nought" or "epsilon zero") is the value of the absolute dielectric permittivity of classical vacuum. Alternatively may be referred to as the permittivity of free space, the electric constant, or the distributed capacitance of the vacuum.

### What is the electric field due to a point charge?

Notice that this is similar to the electric field due to a point charge. Thus outside the sphere, the electric field behaves as though it is due to a point charge (carrying all the charge of the shell) at the centre of the shell. Consider the black Gaussian surface as shown in the figure.
