High-vacuum electron tube with thermionic cathode for demonstrating the thermoelectric effect (Edison effect). Use the tube to investigate the relationship between measured emission current and the voltage applied to the cathode. Also investigate the characteristics of diodes via the process of rectification.
Max. heater voltage: 7.5 V AC/DC
Max. anode voltage: 500 V
Anode current: approx. 2 mA at 200 V (Anode)
Hand-held multimeter for measuring voltage and current for a wide
