Estimate the average drift speed of conduction electrons in a copper wire of across sectional area `1.0 times 10^-7 m^2` carrying a current of 1.5A.Assume the density of conduction electrons to be `9 times 10^28 m^-3`.

Text Solution

Verified by Experts

Average drift speed,
`v=1/( n e A)=1.5/((9times10^28)times(1.6times10^-19)times(1.0 times10^-7))`
`=1.04 times10^-3 m.s^-1`
