Estimate the average drift speed of cond...

Estimate the average drift speed of conduction electrons in a copper wire of cross-sectional area `2.5xx10^(-7)m_(2)` carrying current of 1.8 A. Assume the density of conduction electrons to be `9xx`10^(26)m_(3)`.

Text Solution

Verified by Experts

We know that `V_(d)=I//nqA`.
`(1.8)/((9xx10^(28))xx(1.6xx10^(-19))xx(2.5xx10^(-7)))=5xx10^(-4)ms^(-1)`
