Electron flow in a conducting wire.?I have some confusion regarding the flow of electrons in a wire when voltage is applied across it. Intuitively, i see that when i apply voltage across the ends of the wire say by a battery. The voltage pushes the electrons in the wire. As, a result the electrons flow in straight direction rather than going zig-zag. Some of the electrons reach the positive terminal of the battery, now my query is what happens when the electrons reach the positive terminal.Do they loose all their energy? Also, how is there a constant flow of electrons in the wire because since electrons are flowing constantly from the negative to the positive, is there no instance all the free electrons in the wire have reached the positive terminal? Basically what i mean to say is do the free electrons ever gets extinct? I am sorry if my question sounds stupid but can anyone please explain me a little bit in a conceptual manner?
Well, the wire is connected to a voltage source. When they leave the positive terminal, they go through the wire, then get to the negative terminal. They then flow through the voltage source and back into the wire.
The pace of the electron is variable relying upon the the style of energy you are dealing with. In our case, electrons waft within the conductor, though it's sluggish, it is only like ping-pong balls(Analogous to electrons) inside of a say, plastic pipe slanted down ward. When you provide a bit little bit of strain( i.E. Electrical Voltage or emf in our case) one pushes the other and the other one to the subsequent one so on momentarily (Which is very rapid action). This is how you to find the light turned on immediately once you turn the swap On. I feel is the brief answer for the query. Thank you.
