Answer:
Diameter will be 351.42 mm
Explanation:
We have given current flowing in the copper wire i = 310 A
Voltage drop across the wire V = 0.55 volt
We know that resistance is given by
Length of the copper wire l = 1 m
Resisitivity of the copper wire
We know that resistance
As area
So diameter = 351.42 mm
