An evacuated tube, with electrodes at one end and a screen area at the other.
The inside area of the screen is coated with a phosphor material.
The end of the tube nearest the screen is coated with a conductive paint and an outside Anode connection provided.
At the electrode end a Cathode wire is heated by a heater coil.
Further up the neck of the tube is an anode mesh.
A high negative voltage is applied to the anode connection near the screen.
A positive voltage is applied to the Cathode.
A negative voltage on the first anode causes electron released from the heated cathode to accelerate up the tube towards the screen.
The screen anode causes further acceleration causing electrons to hit the inside of the phosphor coated screen.
The electrons hitting the screen causes the phosphor coating to glow.
The stream of electrons can be deflected using electromagnets arranged around the neck of the tube.
The intensity of the flow of electrons can be controlled by a grid between the cathode and first anode.

What following piece of equipment was used by jj Thomson to find electrons?
J.J. Thomson used a cathode ray tube to discover electrons. By passing an electric current through the tube, he observed the deflection of a beam of electrons, which led to his conclusion about the existence of electrons.
What is the full meaning of CRT in computer?
A "CRT" is a cathode ray tube. An old style computer monitor (not computer).
What is the flow of a cathode ray inside a cathode ray tube?
Electrons.
Who first invented the cathode ray tube?
The cathode ray tube was invented in 1897 by Ferdinand Braun.
Why television are also known as cathode ray tube?
because cathode ray tube is the heart of the television.
When did Cathode ray tube amusement device happen?
Cathode ray tube amusement device happened in 1947.
He conducted the cathode-ray tube experiment?
J.J Thomson conducted the cathode-ray tube experiment in 1911.
Which of these appliances uses cathode ray tube - electric fan refrigerator or rice cooker?
None of these appliances use a cathode ray tube. Older type TVs used a cathode ray tube, its common name was the picture tube.
How was the Cathode Ray Tube Amusement device invented?
Cathode ray tube amusement device was created in 1947.

When should you NOT wear a wrist band ground strap?
when working around an exposed cathode ray tube
What is the negatively charged electrode of a cathode ray tube?
The negatively charged electrode of a cathode ray tube (CRT) is the cathode. The tube is a cathode ray tube, and electrons stream off the cathode, are accelerated across the evacuated space and "directed" either electromagnetically or electrostatically, and then strike the phosphor coating on the positively charged anode at a "location" determined by the "directing" elements.
