One main feeder have two sub feeders (Sub Feeder-A and Sub Feeder-B). If the Sub Feeder-A has demand at a time to be 35 kW and Sub Feeder-B has demand at a time as 42 kW, calculate the total individual maximum demand (MD), the demand of the whole system and the diversity factor if the maximum demand of the main feeder is recorded as 70 kW. Explain the possibility of having the main feeder’s MD to be equal with the sum of both sub feeder’s MD.

Assuming a reciever is located 10km from a 50w transmitter. the carrier frequency is 1900Mhz, free Gr=2, find
I) the power at the receiver,

A particle with charge +7.60 nC is inside a uniform electric field directed to the left. Another force, in addition to the electric force, acts on the particle so that when it is released from rest, it moves to the right. After it has moved 8.00 cm, the additional force has done 6.50∙10^-5 J of work and the particle has 4.35∙10^-5 J of kinetic energy. (a) What work was done by the electric force? (b) What is the potential of the starting point with respect to the end point? (c) What is the magnitude of the electric field?

In a circuit we have a source with 75 W impedance that we want to connect to a 300 W load with a transmission line with characteristic impedance of 75 W. To achieve maximum power transfer an inductor will be connected in series to the source.

a. Use the Smith Chart on the next page to get the minimum length of the line in wavelengths and the inductor reactance value. Write down the values here.

b. Use the input impedance formula, Zin, for a lossless line to get the value of the input impedance with the length given by the Smith Chart.

c. Compare the reactance of the Smith Chart and the formula.

Draw an experiment circuit to produce and measure a 5 kA peak lightning impulse current. In the test circuit, determine the methods of measuring the pulse current, determining the element values and properties according to the current to be measured. Describe one of the methods.

Please provide a digital design circuit modeled in structural verilog that takes two 5-bit inputs (in 2's complement format), and a add/subtract input. If add/subtract = 0 than the circuits ouputs A+B, If add subtract = 1, the circuit outputs A-B (by taking the 2's compliment of B and than adding).
