Question
In the circuit shown in the diagram below, two thick wires connect a 1.6 volt battery to a Nichrome (NiCr) wire. Each thick connecting wire is 16 cm long, and has a radius of 10 mm. The thick wires are made of copper, which has 8.36e+28 mobile electrons per cubic meter, and an electron mobility of 0.00434 (m/s)/(V/m). The Nichrome wire is 5 cm long, and has a radius of 4 mm. Nichrome has 9e+28 mobile electrons per cubic meter, and an electron mobility of 7e-05 (m/s)/(V/m).What is the magnitude of the electric field in the thick copper wire?
V/m
What is the magnitude of the electric field in the thin Nichrome wire?
