A current of I=8.0 A is flowing in a typical extension cord of length L=3.00 m. The cord is made of copper wire with diameter d=1.5 mm. The charge of the electron is e=1.6×10-19 C. The mass of the electron is m=9.1×10−31 kg. The resisitivity of copper is ρ=1.7×10−8 Ω⋅m. The concentration of free electrons in copper is n=8.5×1028 m−3.
Find the total number of collisions (Nc) that all free electrons in this extension cord undergo in one second.
