The 12-gauge copper wire in a typical residential building has a cross-sectional area of 3.31x10^-6 m^2. It carries a constant current of 10A. The conduction electron density in copper is 8.49x10^28 electrons/m^3. What is the drift speed of the electrons?

Step 1
We know the current (I) is 10 A, the cross-sectional area (A) is 3.31x10^{-6} m^2, and the conduction electron density (n) is 8.49x10^{28} electrons/m^3. Show more…

'The 12-gauge copper wire in typical residential building has cross-sectional area of 3.31 X 10-6 m? If it carries current of 10.0 A what is the drift speed of the electrons? Assume that each copper atom contributes one free electron to the current The density of copper is 8.95 g/cm?_'
A copper wire is carrying a current density, J = 3.2x10^6 A/m^2. The free electron density in the copper wire is about n = 8x10^28/m^3. Calculate the drift velocity of the free electrons in the copper wire.
