1. ### A copper wire has radius r = 0.0250 cm, is 3.00 m long, has resistivity ρ = 1.72 x 10-8 Ωm, Physics question will award fave ans! help?

...0.263 Ω b. p.d. = I* R = 0.400A * 0.263Ω = 0.105 V c. field E = p.d. / L = 0.105V / 3.00m = 0.0350... don't see how the charge- carrier density is relevant.
