Shogun:
ure welcome :D ;D

crypsAnity:
@ Shogun nawssss.. ts k .. anyhows

could anybody please tell me how can you use a cro and measure applied voltage?

and the more important one .. the time base right .. whats the difference between it and an xplate to which alternative current is fed?
(if there is any.. because i thto before there wasnt .. but then saw this diagram on the book and got confused because you see there were
two diagrams one which said "after time base on and the current fed to yplates are alternative.." - it was a sine wave ..
and the otehr where i got confused was "after an alternating current being fed to both x and y plates" .. it had and y=x shaped linear graph.. ) help anyone please.. seems like the only stuff in phy dont get .. (so far)

p.s *prays* .. hope CRO's never come ..

Shogun:
umm which book ure having.... i would like to see those graph much clearly...cauz i cant visualize it properly :)

Shogun:
the voltage is calculation depends on the amount of deflection on the y plates on the set input of the yamp gain. so the deflection on the y plates increases the voltage increases. so 1 vertical deflection on the screen shows 1 volts.

Shogun:
what i know about curves is tht if no voltage was supplied the graph would be a stright line parallel tothe x axis.. but if dc current were to be supplied, then a same graph is produced but with different  position (up or down) depending on the postion of the postive charge plate..eg: if postive plates was up and a dc current is supplied so the beam of electron would only deflect on tht side, hence the graph would be same as zero voltage but in different position depending on the beams, deflection.

when an AC current is supplied the postive charge changes its position so the beam of electron deflects in different direction continuosly thus causing a sine curve(up and down, up and down..etc)

this would have the same effect with time base on ,cuz here the position of charge does not change, the amount of voltage changes but i think it would have the same effect as as, excep it would be steepr and sharper turns..
