Not sure if you have had a response on this yet. The point is, the electrons do not actually need to get to the appliance - there are already electrons there. If you think of a simple circuit like a resistor acting as a filament in a light bulb, every stage of that circuit - the power source, the wires, the resistor itself - already has electrons. There is a continuous chain of electrons, all next to each other, at every point in the circuit at all times. What the power source does then is just give the electrons a ‘push’, in line with the voltage of the power source. Each electron then in turn pushes the electrons next to it, all the way through every part of the circuit, until finally the electrons in the filament push on one another and the wire resists the pushing to create the heat / light. This happens nearly instantly. With AC, the push at the start of the cycle just changes to a ‘pull’ at the end on the cycle; it still works exactly the same way, and now every electron in the chain pulls on the electron next to it. Each electron’s actual movement is tiny, so it does not matter if it goes one way or the other. So with a light bulb connected to your AC power socket, it is not the case that electrons move from the generating station travel through the wires to your house and then into the light bulb to make it give off light; all that happens is that the pushes and pulls from the generating station cause the electrons already in the bulb to shake back and forth. It is that movement of the electrons already in the filament that makes the light come on.
😍😍😍😍😍😍
Bro please update.. PLC programming.... video..
dear sir plz shear link the video excitation system in generator
Sir why we go for electrical control panel in case of large industry or substation
⚡👌
👍😘
In ac, electron travel back and forth, then how the electron reach the destination.

@@londonclassicist thanks and appreciate that
@@londonclassicist This is the answer I was looking for. Also it makes sense 👍
