Hi all,

I don't feel too confident at the moment to think about this. I have a set of values which I am supposed to work out some thing. The formula I am supposed to use requires me to convert current (Amps) to Charge (C).

How do I convert Current to Coulombs?

Thanks.

You also need a time. 1 ampere is 1 coulomb per second.
 
Thanks.

What formula would you use to calculate the velocity of charge in a current carrying conductor? I have one but involves force.

You need the density of the free carriers (electrons) in order to calculate the Drift Speed:

http://en.wikipedia.org/wiki/Electric_current

.
 
well you can't find exact velocity as the electrons keep on colliding as they proceed to make current ... but you can find an average velocity with which they would travel

but for that you need average time between 2 successive collisions of an electron ...

and it DONOT require electron density but do need electric field present inside conductor! ... which is yes related to force!

Did you read the link?
 
no
but drift velocity = eEt/2m

you can easily derive this ... and it don't involve any electron density

its current in terms of drift velocity which needs electron density!

Then what is "n" in the link?
I=nAvQ
 
I know that the eqn of wiki is giving a result which involves n but still I'm just saying that v can be found out without using n(electron density)!

I am not disagreeing with wiki and u ! ... Some extra results are always helpful!
