How does a computer produce light?
vacuum tubes designed after WW2 are actual smaller than easy bulbs. the filament many times runs at 6.3 to 12.6 volts at 0.15 to 0.3 amps so 2 watts is a competent usual. the tube is designed to alter plenty intense wattage interior the plate (anode) circuit. an superb potential tube, ie 6L6, is the dimensions of a gentle bulb and could burn up the comparable volume of heat temperature. This tube could be used in an audio potential amplifier for a guitar yet no longer in a working notebook or notebook. The wattage in accordance to tube grew to develop into into truly low in a working notebook or notebook, yet because of certainty thousands of tubes have been needed, it made an superb style of heat temperature and took up an superb style of section. the important undertaking with this form of notebook (noted as first era interior the commerce) is the advise time between failure of a tube grew to develop into into in certainty 10,000 hours. learn that to a 60 watt easy bulb of 1500 hours, yet because of certainty there have been this variety of great style of tubes, the notebook could be down for replacements each couple of hours. specific tubes are even with the certainty that used in broadcast transmitters. they are very great (basketball length) and characteristic cooling fins equipped-in so as that they could be cooled by way of employing great blower followers. those tubes can burn up 1000 to 20000 watts.
interesting. very interesting. you could ask how a phone produces its light, how a tv produces its light. etc anyway. that top contributor sounds like that made sence XD
Is this for like a science thingy? umm the monitor produces light.. and the computer itsself has flashy light on it ^-^ hope this helped? x
Since this is posted under monitors, there are three comon types: the old crt tube like a TV uses an electron beam that makes phosphors on the inside of the tube glow in colors; most LCD flat panels use a fluorescent lamp to provide the light while the LCD part just provides the image; and the newest LCD monitors use a very bright LED (diode) instead of a fluorescent lamp.
