Thanks.
Ralphonsicus said:Yes I know that because electrons have mass and therefore (according to special relativity) they cannot reach light speed. But that wasn't the question, the question was HOW FAST do CRTs shoot electrons (on average)?
Electrons are accelerated in CRTs through the use of an electron gun, which applies a high voltage to a metal plate called the cathode. This causes electrons to be emitted from the cathode and accelerated towards the screen.
The speed of the electrons in a CRT is determined by the strength of the electric field created by the electron gun, as well as the voltage applied to the cathode. The higher the voltage and electric field strength, the faster the electrons will be accelerated.
No, the speed of electrons in a CRT varies depending on the specific location within the tube. As they travel towards the screen, they may be affected by magnetic fields or other factors that can alter their speed.
The speed of electrons in CRTs can vary, but on average they travel at speeds of around 10% of the speed of light, which is approximately 30,000 kilometers per second.
Yes, the speed of electrons in CRTs can be controlled by adjusting the voltage and electric field strength applied to the cathode. This allows for precise control of the electron beam and the display on the screen.
