This paper is devoted to studying the dynamics of the charged spherical stellar model in f(R) gravity. We match the interior region incorporating a perfect fluid with the exterior spacetime through junction conditions and we construct dynamical equations via the Misner-Sharp formalism. The coupling of dynamical equations with the energy of the system describe the rate of collapse for both constant as well as general curvature terms. Finally, we develop a relationship between matter variables, dark source terms and the Weyl scalar. It is concluded that the energy density homogeneity exists if and only if the metric is conformally flat while the rate of collapse is found to be diminishing.
