This paper deals with the dynamics of charged spherical perfect fluid collapse in the framework of gravity. We formulate dynamical equations through the Misner-Sharp formalism and investigate the effects of correction terms, fluid parameters as well as electromagnetic field on the collapse rate. We also construct a relationship among Weyl scalar, correction terms, electric field intensity and energy density. For zero electric charge and constant , it is found that if the metric is conformally flat then energy density is homogeneous and vice versa. We conclude that the electric charge and positive correction terms behave as anti-gravitational force and hence diminish the collapse rate.
