Q3. Suppose that you locate three identical finite wires separated by length d = 1/4 along the z-axis isotropically(no successive phase difference) in such a way that the middle element is placed at the origin. The feeding currentamplitude ratios are 1:2:1. For the Far-Field Zone limit,a) Compute the total Electric Field at an arbitrary point P in space respectively R₁, R, R₂ away from the elements.b) Find the expression for the Normalized Array Factor.c) Calculate the observation angles at which the Nulls of Radiation appear.d) Evaluate the observation angles at which Maxima appears.

We want to figure out when a current is started or stopped in a wire. So we place a small rectangular loop (0.13 by 0.15 meters) a distance 1.3 meters from the wire. If the current in the wire increases by 10 amps/second as it starts flowing, how much potential difference will be induced in the wire loop? Answer in microvolts.

Solar cells generate a potential difference when exposed to sunlight. In an experiment, you wish to charge a rechargeable battery by connecting it in series to an array of solar cells. You perform the experiment outdoors, in direct sunlight, when the intensity of solar radiation is 1000 W/m². However, your solar cells only have an efficiency of 11% (that is, only 11% of the sunlight power transmitted to the solar cells is delivered to the rechargeable battery). While the circuit is connected, you measure at one instant the potential difference across the battery to be 5.30 V and the current in the circuit to be 0.27 A. What is the area of the array of solar cells? m2
