Hey,
I know this is a very trivial thing to know BUT.. Im getting really confused!
First I was told that current flows from the POSTIVE(+) terminal of a battery through a given circuit then to the NEGATIVE (-) terminal..
I was happy!
Then in Chemistry we began electrochemical cells.. here I was told current flows from the NEGATIVE to the POSTIVE!
BTW, When I say current I mean the electron flow direction.. Just making sure Im not completely doing this assbackwards.
Then in physics we learned photoelectric tubes.. again electrons travelled from the negative to the postive terminal.. I asked my teacher which way electrons travel since Ive been told time and time again:
'Electrons travel from postive to negative'
What is postive and what is negative.. ! Since electrons are negatively charged is the negative full of electrons and the postive electron deficent?
ARGH!
Then I began reading about conventional current flow.. !
Can someone please break this down in a very simple manner..
In electronic circuits.. Which way do the electrons travel? When an LED ON which way is the current flowing?
Thank you
