L3-1 [10 marks] Write down the electric field \textbf{E}(x, y, z,t) and magnetic field \textbf{B}(x, y, z,t) for a monochromatic plane wave of amplitude $E_0$, frequency \(\omega\), and phase angle zero that is a) Traveling in the -x direction and polarized in the z direction. (Note: the direction of the \textbf{E} field defines the polarization direction.) b) Traveling in the direction from the origin to the point (-1,-1,-1), with polarization parallel to the xz plane.

A 12-pole DC generator has a simplex wave-wound armature which has 128 coils with 16 turns per coil. The resistance of each turn is 0.022 $\Omega$. Its flux per pole is 0.07 Wb, and the machine is turning at a speed of 360 r/min. Analyse the given information and determine the following: i. Number of current paths in this machine. ii. The induced armature voltage of this machine. iii. The effective armature resistance of this machine? iv. Assuming that a 1.5 k$\Omega$ resistor is connected to the terminals of this generator, investigate the resulting induced counter-torque on the shaft of this machine. (Internal armature resistance of the machine may be ignored).
