The subject is: Smart Grid Please send the answer by typing ONLY. I don't want any handwritten. Q2-Write the applications of Demultiplexer circuits.?

I have an O Gauge track and would like to convert it into a “sensored” track. Additionally, I would like to connect that track to an ESP-WROOM-32 board that should flash an LED whenever the track detects a non-moving train. Please list all the components (and how many of each) needed. Also, what’s the procedure for connecting the components?

GIVE ME THE Numerical value not the formula.. WHATS THE ANSWER IN OHMS ?? Give answer as a Number NOT EQUATION 

Explain and draw a 7490 chip in a circuit of your own design. I want the actual chips drawn with the symbols inside, then a wiring diagram showing the interconnections. Power source and A, B, C, and/or D inputs may be added in the form of either buttons or switches.

Q1. Draw flowchart to find the average of 10 positive numbers. [Hint: Read the number in a loop, add them if it is positive and then find average] Q2. Draw flowchart to read 5 numbers from a user and then find the second largest number of them.

Select the best answer for the question. 4. Look at the drawing shown in the figure above. When you see this drawing in a schematic diagram, you should recognize that it represents a/an O A. step-up transformer. O B. inverter. C. bridge rectifier. OD. thermal relay.

Suppose we include the lead resistance in the calculation of temperature for a class A RTD. If R3 = 1000 ohms, Ra = 18 ohms, V0 = 1.80 volts, and V = 5 volts. Including the tolerances, what is the highest temperature you could measure in °C? (Type in a two-decimal number)

1. For the ADC0804 used in section 1. the step size can be adjusted by setting the reference voltage on pin 9. When this pin is not connected (as shown in the figure 1 schematic), the reference voltage is the operating voltage Vcc. a) What is the step size for this default setting? b) How can we set the reference voltage on pin 9. to 4 V? c) What would be the step size after changing the reference voltage to 4 V? 2. Determine the analog input that will result in an output code of "10001110". Assume 5 V reference. Show your calculations. 3. What value of the analog input voltage would result in a digital output is 6F (hex)? Assume 4V reference. Show calculations. 4. In section, you used a 8-bit D/A converter. With a reference voltage of 5 V, what voltage does each bit represent in terms of the analog output? Show calculations. 5. For the D/A converter, if the output is 3.62 V, what is the value of the digital input? Show calculations. 6. For the D/A converter circuit shown in Figure 2,…

1-What phrase is used when a substitution is permitted for a specific item? 2-The specifications state that all work shall be done... 3-What phrase is used when a substitution is permitted for a specific item? 4-What is the purpose of an electrical symbol? 5. Where are notations found?

No need for further computations. Just give me enough explanation. Thanks!
