Find the total linear momentum of the electrons in a conductor of length `I = 1000m` carrying a current I = 70A.

Text Solution

Verified by Experts

Linear momentum of electrons is
`P = (nmAI)v_d`
where n is the density of electrons, and `v_d` is the drift velocity.
We know.
`v_d = (i)/("ne"A)`
Then linear momentum is `P = nAlm(i)/("ne"A) = (mil)/(e ) = 0.4xx10^(-6) Ns`
