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.
An 18-gauge copper wire (diameter 1.02 mm) carries a current with a current density of 1.20×10^6 A/m^2. Copper has 8.5×10^28 free electrons per cubic meter. Part A: Calculate the current in the wire. Express your answer using two significant figures. Part B: Calculate the drift velocity of electrons in the wire.
