  A numerical model based on Finite Element Method (FEM) has been developed to
simulate the electrical properties of RPC utilizing the law of current
conservation. It has been used to systematically investigate the effect of the
electrical as well as the geometrical parameters of the device components on
the potential distribution and field configuration which govern the RPC
performance. The numerical model has been validated by comparing the dark
current and electric field with those produced by another mathematical model
based on surface currents. The efficacy of the present model has been
demonstrated by comparing its results to the experimental measurements
performed with a glass RPC. The measured and estimated values of these
observables have been found to be in good agreement.
