Question

3.00-m length of copper wire at 20°C has a 1.20-m-long section with diameter
Ten mm and a 1.80-m-long section with diameter 0.80 mm. There is a current of
95 mA in the 1.60-mm diameter section.
the current in the 0.80-mm-diameter section is 2.5 mA
2 the magnitude of E in the 1.60-mm-diameter section is 2.14 x 10- V/m
3) the magnitude of Ē in the 0.80-mm-deameter section is 8.55 x 10% V/n
4) the potential difference between the ends of the 3.00m length of wire is
1.8x10 V​
