Hi all,
A method of thinking I have practised may help you ??...
Put aside one moment all you have been taught about "current flow" and view this situation through a different scenario. Lets look at the simple capacitor. Consider this the "smart" battery that it is. When a capacitor, battery etc is receiving a charge, it "collects" a charge on BOTH plates, the negative "CHARGE" on one and the positive 'CHARGE" on the other. Due to the dialectric the charge doent flow through the capacitor but rather builds up on each plate until there is no more room, so to speak, on each plate. This is proof to the diode effect that developes as a capacitor becomes fully charged per given voltage. Pressure of the voltage . ie the higher the voltage the more pressure. OK - we all know and understand what I have just presented however lets substitute the charges and pressure for something tangible we also understand and similarise this to our "two" directions - types of "current and electron" flow.
If we liken "CHARGE" to people, and lets say that "positive" charges are men, while "negative" charges are women or visa versa, and we cram ALL THE MEN in one room and all the WOMEN in another room - each room being a plate taking the opposite charge. LAWS OF NATURE insist on finding an equilibrium. So now we must have an equal number of men and women in each room. What happens is men will exit their room, walk or run down the passage way to the room where the women are, passing the women who are heading over to the room where the men are leaving, "SAME PATHWAY, OPPOSITE GENDER, OPPOSITE DIRECTION" to find the equilibrium. Lets call their pathway "Current Flow" for the men and "Electron Flow" for the women. Same thing with electricty or "Electric CHARGES"
The measurable standard for "current" is a dirivative or net effect of the two passing influences, ie in a given pathway you may only be able to "fit" 4 people wide during travel - ie "resistance" to movement. Since everyone is travelling as fast as they can to get to their destination with respect to the "GIVEN RESISTANCE" we measure 4 people per branch of particular circuit - OR AMPS. Widening the passageway is like lowering the resistance for the equilibrium to take place quicker hence more people "CHARGE" per given space higher measure of volume ie AMPS.
Equilibrium completes and now no more amps, no flow, no more worry till another "pressure" forces things to move outa place again.
The most important thing to remember is that along the pathway the "negative" and "positive" charges WILL NOT amalgamate. They do not neutralise each other and wont mix, not naturally anyway. Maybe you will need the hole gun from MikeMI to make em mix
Hope this helps.
