Discontinuous currents in two-fluid electromagnetic hydrodynamics (TFEMHD) plasma are considered. Equations for plasma parameters on different sides of discontinuity surface and shock adiabatic equations are derived. Restrictions on plasma parameters behind shock wave surface due to law of entropy growth with discontinuity surface are investigated. The existence of rarefaction shock waves in TFEMHD is shown and the simple necassary and sufficient conditions for one´s are indicated.
