In two-dimensional and three-dimensional conductors, the electric charge distribution takes place over the surface of the conductors. A uniform electric field is a field in which the value of the field strength remains the same at all points. We can easily show that electric field corresponds to a uniform charge density, but it is not simple to explain why, then, a uniform charge density would give rise to such an electric field. Something can be done or not a fit? So my teacher was telling about how if we place an uncharged conducting sphere inside a uniform electric field , the charges so distribute that the E field inside them becomes zero. Uniform means equal distribution. If the amount of electric charge given to a conductor is distributed equally per unit dimension (unit length, unit surface area or unit volume), then the distribution of charge is uniform distribution. Sometimes, it is called continuous charge distribution. can have surface charge distribution of their surfaces. Charge distribution in a sphere in uniform field. To find the electric field due to this sphere, we will use the Gauss law as there is a symmetry in the charge distribution. Electric fields play an important role in a variety of everyday situations.
