having trouble getting my head around a good way of understanding how electronic current works in a basic circuit(a reisistror or light for example), any body have a good way of describing how it works?

Two things, voltage and current.
Voltage is classically called the "electromotive force," that which causes current to flow. No voltage, no current.
Current is determined by the voltage divided by the circuit resistance. Higher resistance, lower current.
Current flowing through certain types of resistors, namely filaments in light bulbs, cause the filament to get so hot that it glows.

think of it like water in a pipe.
the electrons that move in the wire are like water in a pipe.
the bigger the pipe (thicker the wire) the more it can carry.
The higher the pressure (more voltage/amperage), the more water flows (more electrons).
If you have a big pipe that goes into a little pipe (resistor) the water flow slows.
