A current of I=8.0A is flowing in a typical extension cord of length L=3.00m. The cord is made of copper wire with diameter d=1.5mm. The charge of the electron is e=1.6×10−19C. The mass of the electron is me=9.1×10−31kg. The resisitivity of copper is ρ=1.7×10−8Ω⋅m. The concentration of free electrons in copper is n=8.5×1028m−3. Find the drift velocity vd of the electrons in the wire.
