High-vacuum electron tube with thermionic cathode and control grid for demonstrating the thermoelectric effect (Edison effect). Use the tube to investigate the practical applications of a triode as an amplifier and generating undamped oscillations in LC circuits. Also investigate the characteristics of triodes and let students discover the negative electron charge polarity.
