Electrical Engineering

A cylindrical hollow pipe is made of steel (μr = 180 and σ = 4 x10^6 S/m).
The external and internal radii are 7 mm and 5 mm. The length of the tube is 75 m.
The total current I(t) flowing through the pipe is:
I(t)= 8 cos(ωt)

with ω=1200π rad/s
Determine:
d) The intrinsic impedance of the good conductor.

Remember that:
