SUMMARY

The discussion focuses on converting current measured in Amperes to charge in Coulombs, emphasizing that 1 Ampere equals 1 Coulomb per second. Participants also explore the calculation of drift velocity in a current-carrying conductor, highlighting the need for the electric field and average time between electron collisions. The formula for drift velocity is presented as v = eEt/2m, where 'e' is the charge of an electron, 'E' is the electric field, 't' is time, and 'm' is the mass of the electron. The conversation clarifies that while electron density is not required for calculating drift velocity, it is essential for determining current in terms of drift velocity.

PREREQUISITES
  • Understanding of basic electrical concepts, including current and charge.
  • Familiarity with the formula for current: I = nAvQ.
  • Knowledge of drift velocity and its relation to electric fields.
  • Basic physics concepts regarding electron behavior in conductors.
NEXT STEPS
  • Study the relationship between current and charge using the formula I = Q/t.
  • Research the concept of drift velocity and its calculation in conductors.
  • Explore the impact of electric fields on electron motion in conductive materials.
  • Learn about the average time between collisions of electrons in conductors.
USEFUL FOR

Students and professionals in physics, electrical engineering, and anyone interested in understanding the principles of current flow and charge movement in conductors.

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!
