Question: Sections of two wires with a conventional current I = 0.012 A and diameter D = 0.5 mm are shown below. The electron mobility

Sections of two wires with a conventional current I = 0.012 A

Sections of two wires with a conventional current I = 0.012 A and diameter D = 0.5 mm are shown below. The electron mobility in copper is about 4.5 103 (m/s)/(N/C), and the density of mobile electrons is 8.4 1028 m. The electron mobility in nichrome is about 7 x 10-5 (m/s)/(N/C), and the density of mobile electrons is 9 1028 m.
