Design and simulate a regulated power supply using a bridge rectifier, capacitors, and zener diode ( no integrated circuit). The source voltage is 110 plus or minus 10 Vrms, 60 Hz frequency. The output voltage is as follows (plus or minus 5%) : 4.5 V and 12 V

It has to be done on a breadboard. The rating of the adapter will be 12W and 5% regulation. To protect the circuit include a surge protection and fuse in the circuit design. The total cost of the components of the design should be less than $10. A total number of the elements should be less than 12 for reducing environmental impact. Test it on Multisim and breadboard. Please LIST each item that you used on the breadboard test exactly. I NEED YOU TO PERFORM IT ON A BREADBOARD as well as ON MULTISIM. SHOW the multilsim picture. SHOW ALL CALCULATIIONS NEATLY! DO NOT WRITE IN PEN OR CURSIVE! THANK YOU!

1. A given open loop room heating system has a gain of 1.2 and a time constant of 15 seconds. Derive the transfer function of the system in Laplace domain.

2. A closed loop proportional controller was implemented for the system described in Task 1 Q1 above to reduce the time constant to 10 seconds.

a. Draw the block diagram of the system, assuming that the error signal is the difference between the set and actual measured room temperatures.

b. Calculate the gain value (K) of the proportional control action that achieve the above response.

c. Derive the overall closed-loop transfer function in Laplace domain.

analyze the performance of a gasoline engine at various loads based on data given and to determine the torque curve, power curve and performance parameters of BMEP, volumetric efficiency, and Air/fuel ratio, plotting the data vs RPM. Making three graphs: one graphing Torque and Power.

Also address t

a. How do the torque curve and power curve compare (max values @ same RPM)?

b. Is volumetric efficiency constant, or varying with RPM..what is trend?

c. Is BMEP a constant? Does it compare more with torque or power output?

In Taiwan, no one goes to work, and everyone consumes a single good (food), which is imported from another place and can be purchased (one meal at a time) from the nearest vending machine. Alternatively, food can be delivered by a distant catapult, capable of flinging a meal through a customer's window. The price of a delivered catapult meal is $8 and the price of a vending-machine meal is $2. The travel cost for consumers is $1 per roundtrip mile ($0.5 per mile traveled).

a. How many miles would the market area (i.e. maximum miles to be traveled for vending) for the vending machine be?

b. Show your answer in a martini shaped glass, indicating the slope of the glass’ arms, price of food at vending machine, and the radius of the city. (Label your axes)

c. Now assume that everyone owns a bike, which reduces the travel cost to $0.2 per round-trip mile. What would the new market area be for the vending machine?

d. Continue from part c above (everyone owns a bike still). Assume that a new vending machine replaces the old one, now allowing customers to purchase 2 meals at a time (meals are storable at no cost). How would that affect (if any) the market area of the vending machine?

e. Continue from part d above, and assume that everyone eats 2 meals per day in this town, and a month is 30 days long. What would the monthly rent difference be for a residence located 5 miles v. 10 miles away from the vending machine? (Hint: a single daily trip to the vending machine is sufficient).
