Current Attempt in Progress In the circuit shown in the diagram below, two thick wires connect a 1.2 volt battery to a Nichrome (NiCr) wire. Each thick connecting wire is 15 cm long, and has a radius of 11 mm. The thick wires are made of copper, which has 8.36 x 1028 mobile electrons per cubic meter, and an electron mobility of 4.34 x 10'3 (m/s)/(V/m). The Nichrome wire is 6 cm long, and has a radius of 3 mm. Nichrome has 9 x 1028 mobile electrons per cubic meter, and an electron mobility of7 x 10'5 (m/s)/(V/m).
