The triode is a normally "on" device; with zero voltage on the grid current flows to the plate, which is progressively reduced as the grid is made more negative with respect to the cathode.
The plate current is progressively reduced as the grid is made more negative with respect to the cathode. The triode is a normally "on" device; and current flows to the plate with zero voltage on the grid.
