The region between the conductors of a coaxial cable with inner conductor radius a=2m and outer conductor radius b=3m is filled with a material with dielectric constant E. If the charge per unit length of the inner conductor is q, which of the following is the capacitance of the unit length of the coaxial cable.
It is viewed from the cross-section of a coaxial cable consisting of a cylindrical conductive tube with an internal radius R and an outer radius of Rz wrapped around a cylindrical conductive wire with a RADIUS of R. r to indicate the radial distance from the center, the inner cylindrical conductor,if it is j1 = Gr and the outer conductive tube, j2 = Car has improper current densities. Here, the two conductors carry the same I flow in zit directions. What is the size of the B2 magnetic fields at r=1 cm and B2 at r= 8 cm?(R=4 cm; R=7 cm, R3=9 cm; Io=2 A; uo=47.10-7 T.m/A and our aquani-positive forehead outward from the page plane).
Hi, I need help with this question please
Consider a coaxial cable of length l = 50 cm, inner radius of a = 3 cm, and outer radius of b = 5 cm. Due to the conductivity of σ = 0.05 S/m of the dielectric material, a total current of I = 1 mA flows radially outward between the two conductors. Find:a) the current density as a function of r,b) the electric field between the two conductors as a function of r, c) the voltage between the two conductors.
