A three-phase motor is delta connected to a 415 V, 60 Hz line. If the line current is 25 A and the motor power factor is 0.75, how much power is consumed by the motor (a) Determine the size of the bank of three capacitors to improve the power factor of the motor to 0.95. The capacitors are delta connected. (b) If two of the motors work together, what is the size of capacitors to correct the power factor to 0.95 if delta connected?

Verify the operation of a D flip-flop by providing appropriate inputs to the D, Preset, and Clear pins. Use CLOCK input to the flip-flop to function properly ( can be found under wiring in Logisim)

//If you present a diagram designed in the "Logisim app" it would be very much appreciated. Thank you

Draw circuit schematic of DRAM and answer the following questions

▪ Why NMOS is used as a pass transistor in the conventional DRAM, not PMOS?
▪ Explain how capacitor retain data in DRAM
▪ If PMOS is used in DRAM instead of NMOS, suggest a method to increase its performance. Provide reason to support your answer

For a 2-input NAND gate, determine transistor sizes such that the effective resistances for charging and discharging are comparable to those of the reference inverter. Then estimate its worst-case input-to-output delay, a.k.a. propagation delay, for rising output transition ( ? pdr.est).

Coin toss experiment In this experiment, determine the number of heads and tails after flipping a coin for 1000 times. Use two different methods to find number of heads and tails Use for loops Use vectors in MATLAB. Repeat this experiment to find running average of flipping a coin for 200 and 2000 times. Plot the running average for two experiments using subplot functions

if you are designing a photovoltaic solar system for a university building, estimate the total load for the building. please show the different loads for each component ( projector, computer, lights, printers,etc...) in watts? how many of these are in the building and whats the total load? assume the building area?

Interpolation Filters. Write a Matlab program to read and upsample the linked voice_samp_8k.wav file (below -- sampled at Fs=8000 samples per second) by an integer factor L (you can choose, probably in the range from 3 to 7 or so). Then use interpolation filtering to produce the following outputs and listen to them and plot short segments (~50-100 samples) of these outputs: (i) upsample only with no interpolation filtering, (ii) hold interpolation implemented directly as a causal FIR filter, (iii) linear interpolation implemented directly as a causal FIR filter, and two other designed FIR lowpass interpolation filtering with (iv) shorter (~20-200) FIR filters and (v) longer (~200-2000) FIR filters that you design with fir1(). Verify that your program is doing what you want by looking at plots of the various outputs. Also note any interesting observations.

3. A 60Hz, single phase line transmits power to an inductive load that has a receiving voltage of 13.8KV, reactive factor of 0.6 and 5 MVA respectively. If this line has a impedance of 1+j2 ohms per conductor, Calculate the following: The voltage at the sending end (10 pts) b. The transmission line efficiency (10 pts) c. If this line is connected in parallel to a telephone wire and the conductors of the power line is labelled a and b and on the telephone wire 1 and 2 respectively. The power lines has a horizontal distance of 5m and the telephone wire is symmetrically positioned 3m below conductor 'b' with the telephone wires having 2m spacing.

Mr. Ndugu is using a HC-SR505 PIR motion sensor module in a lab project. Please suggest Mr. Ndugu a proper way to connect this sensor to the Open1768 development board (i.e. to which pins, etc …) and to configure the selected pins! (4 points) Write a c code and let us assume that Mr. Ndugu wants to detect a rising edge of a signal generated by the sensor over the pin P2.7 (Pin 7 of Port2) (6points). later change the c code lines in such a way tat the LED0 &LED1 on the Open 1768 development board are switched ON while LED1 and LED2 are switched OFF if a rising edge is detected on pin P2.7(5points)
