In the demonstration of the electrostatic effect cathode ray tube, the switch of the low-voltage power supply and the rotating induction coil is first turned on to generate the cathode ray, and a belt-shaped track appears on the fluorescent plate.2. Then, the DC high-voltage current is turned on to form an electric field. At this time, when the cathode ray passes through the fluorescent plate, the strip track is deflected toward the electrode plate having a high potential.3. With the change of the output voltage of the regulating transformer (that is, the change of the electric field strength caused by the change of the DC high voltage), the deflection angle of the strip track also changes.4. According to the case where the cathode ray is deflected in the electric field, it can be confirmed that the cathode ray is a stream of particles that help the charge, and the negatively charged particles are electrons.Size: length 300*height 195mmNote:Size For Manual Measurement, there may be a 0 to 2 cm error, belongs to the normal phenomenon.And due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!
