[QUOTE="ghostinthemachine, post: 37750, member: 760"] So what happens next? Take a vacuum tube diode and place a fine metal grid between the ANODE (plate) and CATHODE. Now you have a triode. When the grid's potential equals that of the cathode (NEGATIVELY CHARGED) no electrons can pass through to the plate or CATHODE. So we will have no electron flow. But if we make the grid more positive than the CATHODE electrons will rush towards and then past the GRID. We now have some control over the flow of these billions of tiny electrons. [/QUOTE]
