1.A copper cylindrical wire which has a radius of 1.2 * 10 -3m carries a constant current of 6.0 A. Assume each copper atom contributes one free electron. The density of copper is 8.93 g/cm3. Calculate the following:
a.Drift velocity, vD, (m/s)
b.Resistance (Ω) of a 2 meter segment of this wire at room temperature
You will need to look up the following:
1. molar mass of copper, 2. resistivity of copper @ room temp, 3.
Avogadro’s number
Homework Answers
a)
Drift velocity
Vd = I/nAq
Vd = 6/(8930x6x10^23 x1.6x10^-19)
Vd = 0.000000006 m/sec
b)
resistivity = 1.7 x 10-8
R = resistivity x L/A
R = 0.00751565 ohm
