    A cathode ray tube (CRT) is used by almost all TV sets today to display the onscreen images. A cathode (Item A) is a negative terminal while an anode (Item C) is a positive terminal. In the image below, the cathode is a heated filament, which is an electrical conducting wire, encased in a vacuum inside the glass tube. The heated cathode naturally produces a stream of electrons, or a ray (Item E), that pours off into the vacuum. The anode, being positive, attracts the engative electrons and then focuses and accelerates them into a tight, high-speed beam that then travels through the vacuum to the phosphor-coated screen (Item D), which glows when hit by the beam, creating the final image!Cathode Ray Tube: A breakdown of how the parts of a cathode ray tube work together to create an imageCathode Ray Tube: A breakdown of how the parts of a cathode ray tube work together to create an image
