The electric field in a parallel plate condenser remains unchanged with varying distance between the plates. This is because the electric field only depends on the charge density on the plates and the permittivity of the material between the plates, not the distance between the plates.
The equation for calculating the electric field in a parallel plate condenser is E = σ/ε0, where E is the electric field, σ is the charge density on the plates, and ε0 is the permittivity of free space.
The electric field is constant in a parallel plate condenser because the electric field lines between the plates are parallel and equidistant, resulting in a uniform electric field.
Yes, the electric field can change in a parallel plate condenser with varying distance if there is a dielectric material between the plates. The presence of a dielectric material changes the permittivity between the plates, thus altering the electric field.
The area of the plates does not affect the electric field in a parallel plate condenser. As long as the distance between the plates and the charge density on the plates remain constant, the electric field will also remain constant.
