. Which were these bulky evacuated glass bulbs. The triode vacuum tube consisted of tubes parts, the cathode, grid and anode. A current is passed trought the cathode and it begins to up, causing it to three electrons, as the gases have been removed from the tube the electrons have very little to their movement and they are attracted to the positive heat release charged anode. This completes the and a current flows. But we can this flow of electrons in many useful with the resistence grid. circuit
