Jump to... mmunity College- PHY 122 -Summer17-GERLITZ | Activities and Due Dates | HW. Current and Resistance Not Set 0/100 Gradebook Print Calculator-Periodic Table Question 1 of 15 Sapling Learning Map When a current flows in an aluminum wire of diameter 3.67 mm, the drift speed of the conduction electrons is 1.77 x104 m/s. How many electrons are flowing past a given point each second? The conduction electron density in aluminum is 6.00 x 108 m-3 Number terms of use contect hel Gbocareersprvacy polcy @ rch

Explanation / Answer

Current , i = neAv

So, i/e = nAv = 6*10^28*pi*(0.00367)^2*1.77*10^-4

= 4.493 * 10^20 S-1
