remember that if an electron (or any other negatively charged particle) is going one way then the current going the opposite way
so if an electron is moving like this:
then the current is in this direction:
i hope i didnt confuse you... its just a common mistake thats worth pointing out imo...
lol. I'm the only one at my school doing nuclear & particle physics, everyone else is doing cosmology (my class is at a different school due to timetable clashes, it's a consortium, don'tcha know...). So I'm probably gonna be sitting there alone working out the direction of a proton while they're off describing the life cycles of stars...
haha i remember doing the left hand rule and our physics teacher got really excited about it! he used to rise to his tiptoes on the stressed bits of the words: ffffffffffffffirst ffffffffffffinger = fffffffffield
seCond finger = Current
thummmmmmmmb = mmmmmotion
and he had a broad yorkshire accent so the mmmooootion got him really excited. bless him! he then retired and made his attic into a weather station.
