The resistance-temperature relationship of an NTC thermistor can be approximately described using the following equation:
R(T)= a*exp(B/T), a=0.1865 & B=2,946K
Design a voltage divider as the signal conditioning circuit for the negative temperature coefficient thermistor. Your circuit should use a 5v power supply. It should produce a positive voltage signal with a reading of approximately 4v at 100 degrees Celsius and the lower readings at lower temperatures. Draw the circuit schematic. Use the symbol for an adjustable resistor to represent the thermistor. Specify the values of each component in the voltage divider. show your calculations.

ASAP In this lab, you will make a digital thermometer using the SEN-11931 breakout board as well as the 4-bank seven-segment LED display. Design the hardware connection of the SEN-11931, reuse the 4-bank 7-segment LED connection from Lab 4 for the mbed to read the temperature from the SEN-11931 and display the temperature in Fahrenheit degrees on the LED display in the format of xxx.x. Build your circuit and include all the required information about your hardware design in your lab report. You will also need to make the decision on whether pull-up resistors are needed. Based on the hardware you designed, write a code that takes temperature measurement every 5 seconds and display the temperature in Fahrenheit degrees in the format of xxx.x (for example: 098.6 or 104.8) on the 4-bank seven-segment LED display.

Develop a series RLC circuit that increases the capacitor voltage to the source voltage as fast as possible with no more than a 20% overshoot. The source voltage is 99V, the capacitance is 9F the and the inductance is 23 H. You can adjust the resistance since that the inductance are the two easiest parameters to adjust. I suggest you find ω0 for your circuit and the value of R that results in a critically damped circuit. Plot this vs. time using Δt ≈ 0.1/ω0. Plot the under damped response on the same set of axes. Hint – the resistance will be lower than for the critically damped circuit. Adjust the resistance to so that the capacitor voltage reaches the source voltage as soon as possible without overshooting by more than 20%.
