  The working of a resistive plate chamber depends on the electric field
applied inside the gas gap. The strength of this electric field inside the gas
gap depends on parameters like electrode thickness, permittivity, gas gap,
among others. The applied electric field can get significantly modified by
space charge effect. This can be a major concern while working in high rate
particle physics experiments. Accumulation of space charge generated due to
consecutive avalanches can distort the applied field. During this
investigation, we have observed that the strength of this perturbation in
electric field is a function of the amount of charge, electrode thickness,
permittivity, and gas gap.
  In this paper, we have studied the dependence of the applied field on
parameters linked to RPC fabrication, mentioned above. In addition, we have
used the method of image to calculate the additional polarisation field due to
space charge for a basic five layers of the geometry of an RPC. The variation
of the perturbation in electric field with the same three parameters electrode
thickness, permittivity, gas gap has also been discussed.
