Strength of Electric field is given by:
E = rho*J
rho = resistivity of copper = 1.72*10^-8 ohm-m
J = current density = i/A
E = rho*i/A
A = pi*d^2/4
Using given values:
E = 1.72*10^-8*4.50/(pi*(2.05*10^-3)^2/4)
E = 0.02345 V/m
E = 2.345*10^-2 V/m
Correct option is E.

1. What is the resistance at normal room temperature of 60 m of copper wire having a diameter of 0.64 mm? (r copper = 1.7241 X 10^-8 at 20 C) 2. A semi-circular copper conductor has an inner radius of 60 cm, an axial thickness of 4 cm and a radial thickness of 3 cm. Determine the resistance of this conductor between its two end contact faces at 70 C
show work please The maximum sustainable electric field strength in air is 3.0 x 106 V/m. (electric fields above this field strength will ionize the air and cause sparks to form). Find the magnitude of the maximum potential difference that can therefore be sustained between two parallel conducting plates separated by 1.49 cm of air. Select the correct answer O 13.1 kV O 54.6 kV 0 20.1 kV 44.7kV 33.3kV
