Quoted from Star_Gazer:How do you know the right direction the current flows with these Lamps (resistors) ?

I'm pretty sure resistors/lamps aren't directional. However for LED's polarity does matter because they are diodes.
Quoted from Star_Gazer:But a resistor works only one way right? Or isn't a light not really an resistor?
An LED is a light emitting DIODE, and polarity matters on diodes because they only allow the flow of current in a single direction.
Incandescent bulbs are basically resistors, because a filament is just a coil of wire. And resistors are basically just (calculated) coils of wire too.
Quoted from urbanledge:Yes. This is correct but either way the voltage doesn't change.
I think the graphics were meant to show that if you wired the bulbs in series, you would need an 18v power source for 3 6v bulbs.
Quoted from Andy_B:OP I don't want to rain on your parade but you are a person who has "trouble understanding that electricity stuff" yet you want to provide a guide for people who also have trouble understanding that electricity stuff too? And inviting comments/suggestions from other members of the group some of whom clearly have a little trouble understanding that electricity stuff too???
It's gonna be a long road.....

I think you misunderstood OP's intention.
He said he is more of a visual learner, so the images he is making are questions that he is posing to learn for himself. Not to teach people (until the question is answered correctly I guess).

Quoted from robertmee:Diodes are an important component of bridge rectifiers, which are used to convert all Pinball machines incoming AC voltage to useful DC voltages.
