A 200 volt (r. m. s) generator having an internal resistance of 200 ohm is feeding a loss-less transmission line. The characteristic impedance and the length of the line are 200 ohm and 10 m respectively. The line is terminated in a resistive load of 100 ohm. If the operating frequency is 37.5 MHz calculate the
Current drawn from the generator.
Magnitude and phase of the current flowing in the load.
Power delivered to the load.

Two isotropic antennas are separated by a distance of two wavelengths. If both the antennas are fed with currents of equal phase and magnitude, the number of lobes in the radiation pattern in the horizontal plane are

The incoming solar radiation at a place on the surface of the earth is 1.2 KW/m².The amplitude of the electric field corresponding to this incident power is nearly equal to
