wheater there is electric field inside a conductor .?
If no . how does electric field then contribute to the acceleration of the electrons ??
plz give and appropriate reason for this ..
i m really confused.?
rates assured .

wat is the problem?
wat do u mean by accelarating of electrons?
they will accelarate on surface only when an external electric field is present(in case of conductor)

i had said external electric field..............plz see that.............
in electrostatic cond it is 0 inside the conductor

So what it would be the electric field inside a conductor between a certain potential diffrence ?
and the electrons would be in random motion in the entire volume of the conductor . ?

see under electrostatic conditions there is no electric fiels inside thef conductor....why???
because electonsget accumulated at the surface in such a way that electric field vector of the fielfd produced is such that it is equal and opposite to the external field and hence it is zero(nice explanation is given in hc verma)
but if we make a patha for the accumulated electron to flow..they will flow as soon a s they reach tha hypothetical surface(now)..hence electric field caused the drift of electron...

so that means electrons dont flow within the volume of the conductor.......

c
d elctric field inside a conductor is zero
wen an xternal feild is applied then induction takes place inside d conductor and negative and positive charges get seprated and internal ectric field is created bt very soon (couple a milii sec) this int field gets = to d xtrnal field
bt c if d xternal field is to d left d intrnal field is towards rite
so they cancell each other
thus currnt inside =zero...
this is applicable evn wen their is no xternal currnt coz d tym for this 2 happn is very small

@zohairsayyid
current flows through entire volume of counductor..
if we apply electric field parallel to the courved surface of the cylinder..electons would accumulate at one of the ends of the cylinder...
that is what i was trying to say in my previous post..
if we provide a path for the electrons to flow at the flat surface of the cylinder, they will flow from the flat surface of the cylinder...but inside the cylinder they flow through the entire volume..
hope its clear now..

hey yaaar ,,,
sorry but ,,,,,
one more question ,
how does the electric field and the potential difference are related in context with the drift velocity ...
rates assured ....
