The grid leak used in radio engineering often is an ink film. Is it used as a path of escape of electrons from the grid. This path is necessary, for electrons collect on the grid and cause it to become negatively charged. Since a vacuum tube will not function unless the grid is charged positively with respect to the filiament, the necessity of the grid leak is obvious. The rate of absorption of electrons by the grid, and of their removal by the grid leak can be controlled to a certain extent by varying this grid leak resistance.
