It is not something which would eat away currrent, it would rather limit the flow of electrons, reducing the intensty of flow of electrons, the Resistor is used in a circuit to oppose an electric current by producing a voltage drop between its terminals in proportion to the current.

It works accordingly to the ohms law.
