Estimate the average drift velocity of conduction electrons in a coppe

1.	Estimate the average drift velocity of conduction electrons in a copper wire of cross-sectional area `2.5 xx 10^(-7) m^(2)`, carrying a current of 2.7 A. Assume the density of conduction electrons to be `9 xx 10^(28) m^(-3)`.
Answer» Correct Answer - `0.75 mms^(-1)` `upsilon_(d) = (I)/(nAe)` `(2.7)/((9 xx 10^(28)) xx (2.5 xx 10^(-7)) xx (1.6xx 10^(-19)))` `= 0.75 xx 10^(-3)ms^(-1) = 0.75 "mms"^(-1)`
