Why is Current same in series? The reason is said : charges cannot accumulate ,, thats why ,,,,,But any better answer,,,,,,,,,,,like, i want to know why the the electrons cant ZOOM thru the connecting wires and then go SLOWLY thru the resistors,,,,

Why is Current same in series?   The reason is said : charges cannot accumulate ,, thats why ,,,,,But any better answer,,,,,,,,,,,like, i want to know why the the electrons cant ZOOM thru the connecting wires and then go SLOWLY thru  the resistors,,,,

anonymous · Answer

But actually , the electrons are SUPPOSED to move with the same rate it seems.....

anonymous · Answer

PLEASE PLEASE dont take the analogy of water flowing in the tube,,,,im tired of that

anonymous · Answer

is it bcos density of electrons is SAME ALWAYS? even when current flows?

lastdaywork · Answer

Have you heard the phrase "steady state" ??

anonymous · Answer

ya....DC ,,equilibrium state

anonymous · Answer

not exactly

lastdaywork · Answer

In thermal conduction ?

anonymous · Answer

no....:(

anonymous · Answer

thermal motion u say?

anonymous · Answer

i think i know somewhat......the random motion of electrons

lastdaywork · Answer

I meant, conduction of heat due to a temperature difference..

anonymous · Answer

ok,,,,the vibrations of the electrons are passed on....?

anonymous · Answer

until all of them vibrate ,,and heat up the conductor?

lastdaywork · Answer

Never mind,

Lets get back to electricity.
"charges cannot accumulate" because like charges repel each other.

anonymous · Answer

ohk!

anonymous · Answer

so when they are moving at the same rate in forward direction , they dont feel the repulsion from other fellow electrons that are also moving?

lastdaywork · Answer

The (net) movement of charges is due to the presence of electric field.
Also, for any electron; the net force of repulsion due to all other electrons will be more or less nullified.

anonymous · Answer

ok....

lastdaywork · Answer

Er..sorry
There is a better explanation.
As there is NO localization of charge; every segment of the wire would be more-or-less neutral.

anonymous · Answer

ok,,,so when current flows in a conductor, the conductor MUST be neutral   ?

anonymous · Answer

all the parts?

lastdaywork · Answer

I was talking about steady-state.

anonymous · Answer

ok, i get it now,, when there is accumulation of charge , then there will be charge separation within the conductor,,, which is not allowed

anonymous · Answer

Thanks a lot

lastdaywork · Answer

If there is a charge accumulation (in the beginning) , it will start de-localizing all over the conductor.

lastdaywork · Answer

Finally, we'll achieve steady-state; where there would be no excess charge inside the conductor. Note that excess charge may reside on the outer boundary of the conductor.
