![]() d) What will happen to the electrons when it hit the fluorescent screen? Explain. Cathode ray tube deflection circuit using an insulated gate bipolar transistor driver. c) What will happen to the electrons when it passed through the deflecting coil? Explain. I like to think of it like a sphere shaped chocolate chip cookie since plum pudding is not super popular in the US. With the diagrams below, you need to explain how this CRT technology is possible to create the colours on the TV screen and you need to explain what will happen to the CRT technology if a strong magnet is brought near the screen, Anode Deflecting coils Control Grid (a) (b) (d) (c) Fluorescent screen Heater Cathode Electron beam Focusing coil a) What will happen to the cathode when it is heated? b) What will happen to electrons when it passed through the focusing coil? Explain. Heavy Metals: CRT monitors and TVs can contain anywhere from 2 to 5 pounds of lead per unit Color CRT may contain mercury. A break in the tube which is fragile at the neck behind the screen, causes an implosion followed by an explosion of glass. This article gives the advantages and disadvantages of CRT to give more information about CRT. It is less bulky, as well as used in various applications. The residual gas pressure is comparatively high, as clinical tubes are not subject to active evacuation during operation. The X-ray focal spot on the anode in view of the cathode may generate metallic and other vapors. It is less bulky, as well as used in various applications. Cathodes of typical medical diagnostic X-ray tubes operate under adverse conditions. The people around that time were happy to watch a TV with colours. Risk of Explosion: As implied in the name, the tube of the CTR is under vacuum. CRT full form stands for cathode ray tube also known as the picture tube. Surprisingly, this CRT technology managed to make the TV screen appeared with colours instead of black and white. ![]() It became popular from time to time with several adjustments at CRT. ![]() In 1934, television sets with cathode-ray tubes (CRT) were first manufactured in Germany.
