B1 *Problem 8Consider a three-phase transmission line consisting of three concentric con-ductors, as shown in the figure. The spaces between the conductors areempty and the currents carried by the three conductors are:I = I, cos(kz - wt)I2 = Io cos(kz – wt + 27/3)%3DI3 = Io cos(kz – wt + 4/3)(a) Compute the electric and magnetic fields of the TEM wave propagatingdown this wire for all three regions.(b) Compute the total power carried down this cable by the electromag-netic wave.I3

To answer: The electric and magnetic field comparision Total power

The spaces between the conductors are empty and the currents carried by the three conductors are: I = I, cos(kz – wt) %3| I2 = Io cos(kz –wt + 27/3) Iz = I, cos(kz – wt + 47/3) (a) Compute the electric and magnetic fields of the TEM wave propagating down this wire for all three regions. (b) Compute the total power carried down this cable by the electromag- netic wave.
