The 16-gauge copper wire with radius 5.1 x 10-4 m and its area of cross section is 8.20 x 10-7 m 2. The amount of electric current is 1.67 ampere passing through in it.
Calculate (a) The magnitude of electric field in the wire (b) The electric potential difference between two points 50 x 103 m apart. (c) What is the resistance of 50 m length of copper wire? Whereas the resistivity of copper wire is 1.72 x 10-8 Ω.
