In this paper, the effect of electromagnetic field has been investigated onthe spherically symmetric collapse with the perfect fluid in the presence ofpositive cosmological constant. Junction conditions between the static exteriorand non-static interior spherically symmetric spacetimes are discussed. Westudy the apparent horizons and their physical significance. It is found thatelectromagnetic field reduces the bound of cosmological constant by reducingthe pressure and hence collapsing process is faster as compared to the perfectfluid case. This work gives the generalization of the perfect fluid case to thecharged perfect fluid. Results for the perfect fluid case are recovered.
