Brand : ERoomQ
BulletPoint1 : 1. Electrostatic effect cathode ray tube: Demonstrates the phenomenon that the cathode ray deflects in the electric field, and proves that the cathode ray is a negatively charged particle stream (ie, electron flow).
BulletPoint2 : 2. With the change of the output voltage of the voltage 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.
BulletPoint3 : 3. Electrostatic effect The cathode ray tube is composed of a bulb, a baffle plate, a fluorescent plate, an electric field electrode, a cathode, an anode, a bakelite seat and the like.
BulletPoint4 : 4. Electrostatic effect The cathode ray tube is turned on, and the switch of the low-voltage power supply and the rotating induction coil is first turned on to generate cathode ray, and a belt-shaped track appears on the fluorescent plate. Then, the DC high-voltage current is turned on to form an electric field, and when the cathode ray passes through the fluorescent plate, the strip track is deflected toward the electrode plate having a high potential.
BulletPoint5 : 5. 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.

ProductDescription : First, use: Electrostatic effect cathode ray tube: Demonstrates the phenomenon that the cathode ray deflects in the electric field, which proves that the cathode ray is a negatively charged particle stream (ie, electron flow). Second, the structure The electrostatic radiation cathode ray tube is composed of a bulb, a baffle plate, a fluorescent plate, an electric field electrode, a cathode, an anode, a bakelite, and the like. Third, demonstrate environmental conditions 1. 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.
