A copper wire has a diameter of 1.02 mm, cross-sectional area 8.2x10-7 m2 and resistivity 1.72 x 10-82 m. It carries a current 1.67 A. Find the electric field magnitude in the wire and the potential difference between two points in the wire 50 m apart. [4] ​

science is a systematic and logical approach to discovering how things in the universe work. true to this definition, science aims for measurable results through testing and analysis. science is based on fact, not opinion or preferences. the process of science is designed to challenge ideas through research.
