A voltmeter ( i think it was a voltmeter. dont remember exactly :P but has to do with volts :P) is attached to the y-plates

--- Quote from: Baladya on May 26, 2010, 10:16:20 pm ---Cathode is heated and shoots electrons at high speed (and energy). It is the thing on the left. Then the anode atracts the electron and makes the electron pass through a gap in it. Then u've got the y-plates which move the electron up and down by + and -plates .(postitive attracts electron, negative deflects it. X-plates same thing but left and right. Then there is a Fluorescent screen which gives light when the electron hit it. A time-based circuit is connected to X-plates to move the dot (the dot shown on the screen) left to right at a constant speeed and then returns it very quickly to the start.
