The self-field and the associated plasma response of an externally injected charged particle in plasmas are investigated within a self-consistent formalism that extends a formula used in plasma wake-field acceleration. The response of plasmas to such a self-field is also investigated through this self-consistent theory. This self-consistent theory leads to a correct formula of plasma wake field.
