Whаt is the drift velоcity оf electrоns in а copper wire of diаmeter 1.628 mm carrying 20.0 A of current? The density of free electrons is calculated to be 8.34 x 1028 electrons/m3. The charge of an electron is -e (-1.60 x 10-19C). If a copper wire of diameter of 2.304 mm is used, what is the drift velocity? Why are the drift velocities you calculated MUCH less than the signal speed in the order of 108 m/s? (3 points).
