Behavior of one electron choosing a path

[danielhaish]

I know that current chose the way with the lowest resistance but this is becouse that few electrons will go on the two path and the smallest number of electron .,Is the path that the current go throw . But how does a single elelctrons "choose" is path .
And also if I connect two wire to a battary from both side instead of one deos it will change the voltage the amper or is it will empty it faster

What experiment are you talking about?

 

[danielhaish]

I am not talking about experience i asked how single elelctron behave in two option of path would it behave like current or it will choose the path randomally

 

[PeterDonis]

I am not talking about experience

I didn't say "experience", I said "experiment".

how single elelctron behave in two option of path

What experiment are you talking about? You need to describe specifically what the experimental setup is and how it gives a single electron two options for a path to take. Otherwise your question is not well-defined and therefore not answerable.

I think I may know in a general way what you mean (resisters in parallel) but it will save a lot of aggravation and time for us all if you ask a well-specified question.

If that's what the OP means, this thread belongs in Classical Physics, not Quantum Physics.

 

[hutchphd]

If that is his intent, perhaps we need to explain why that is true! But as you requested he needs to specify the question first..

 

[danielhaish]

Ok so this is the condition there surfaces that nagtive charge in one elctrons is connect with two wires to surface that have positive charge or nutral . And my question is in which wire the electron goes is it will be randomally one or the one wirh the smallest resestance

 

[hutchphd]

There are of course many many electrons involved in any macroscopic current and a lot of interactions along the way...if you are thinking about quantum probabilities they will not really show up here. For instance the electron you put into the wire will not usually be the electron you measure. But at finite temperature for ordinary conductors one can describe the "probability of measuring an electron (per time interval) as current". And ohm's law is certainly true.

 

[Nugatory]

Ok, sounds like you’re thinking classical not quantum mechanics, so this thread is moved to the classical physics forum.

 

[danielhaish]

Yesh but if there is only one elctron he mist go only at once wire

 

[hutchphd]

But there are many many electrons already in the wire. You cannot point to one.

There will be an electrical force on the electron, and the electron will go in whichever direction that force pushes it. The force comes from all the other charged particles around the electron. The forces will be such that more electrons get pushed down the low resistance path than the high resistance path.

The detailed calculation involving the interactions of every one of quadrillions of quadrillions of charged particles are completely impractical, which is why we think in terms of current flow instead of the motion of individual electrons to analyze circuits.
