A 12 gauge copper wire has a cross sectional area of 3.31 x 10-6 m2. What is the drift velocity of electrons in this wire when it carries a current of 2.5 A? (Recall the example from the text that found the number density of electrons in copper available for carrying current is 8.5 x 1028 /m3.)
Added by Sandra N.
Step 1
Step 1: Recall the formula for drift velocity: \(V_D = \frac{I}{n_eA}\), where \(I\) is the current, \(n_e\) is the number density of electrons, and \(A\) is the cross-sectional area of the wire. Show more…

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?

A 10 gauge copper wire carries a current of 26 A. Assuming one free electron per copper atom, calculate the drift velocity of the electrons. (The cross-sectional area of a 10-gauge wire is 5.261 mm2.) mm/s

An 18 -gauge copper wire (diameter 1.02 $\mathrm{mm} )$ carries a current with a current density of $1.50 \times 10^{6} \mathrm{A} / \mathrm{m}^{2} .$ The density of free electrons for copper is $8.5 \times 10^{28}$ electrons per cubic meter. ,Calculate (a) the current in the wire and (b) the drift velocity of electrons in the wire.
