how electricity works?

I was directed here the other day for a wiring problem it may have the answers your looking for

http://www.allaboutcircuits.com/worksheets/index.h...

theres a lot of info in the work sheets but i haven't read it all yet

hope this helps

an electrical circuit is the flow of electrons through a controlled circuit from a source (battery/cell)

series:

a one-cycle circuit that has only one path and can be controlled by only one switch.

-if the switch were to be turned off the whole circuit would stop.

-voltage changes(not always equally however)

-amperes stays constant throughout the circuit

parallel:

a circuit that can be separated into different paths or branches to control multiple different loads.

-voltage is always constant in these.

-amperes changes per path or load.

-total amperes of circuit = the amount of branches in the circuit (unless otherwise indicated).
