So what i can get from your answer is that say 1 terminal is positive then it becomes negative then again positive and so on... But there's just one problem. Won't it just move backwards and forwards (the current)?? Like one step ahead then 1 step back?? LOL :D.
(Please really sorry to disturb all of you guys but I've never understood this (from Grade 6) and I believe if I don't clear this doubt now, it'll haunt me for the rest of my life)...

nonono! haha, look, the current for the first round will move from positive to negative terminal , next, it will move from negative to positive, this keeps on happening..

People. I am sleepy, I feel drunk and I really want to go to SLEEEP !!!
So please answer this question of mine before I smash the laptop :
Why is it 600 V DC between the cathode and anode of a CRO ???
Specifically WHY DC ?? WHY NOT AC

dude u cant have alternating POLES for A CRO!!!!!!
do u want the elctrons to keep flyin form one directio another??
no
for DC
U HAVE 1 FIXED NEGATIVE POLE ( CATHODE ) AND ONE ANODE ( POSOTIVE)
ELECTRONS MOVE FROOM NEGATIVE TO POSOTIVE
