Question: Task # 0 9 : Design a circuit that will read the voltage output of a thermistor for both an NTC and a PTC
Task#: Design a circuit that will read the voltage output of a thermistor for both an NTC and a PTC thermistor.
The following Hints should be used for NTC and PTC Thermistor Circuits:
NTC Negative Temperature Coefficient Thermistor: Its resistance decreases as temperature increases. For your circuit design, you can use a potential divider circuit where the thermistor is one of the resistive elements. This allows you to measure the change in voltage across the thermistor as the temperature changes.
PTC Positive Temperature Coefficient Thermistor: Its resistance increases with temperature. Design a similar potential divider circuit, but consider how the voltage output will change differently compared to the NTC thermistor.
For both circuits, you'll need to connect the thermistor in series with a fixed resistor and apply a known voltage. Measure the output voltage across the thermistor to observe how it varies with temperature changes from circmathrmC to circmathrmC
Software Simulation: Use software Multisim to simulate the circuit over the temperature range. This will allow you to observe how the voltage changes with temperature and compare the behavior on plotted graph for both the NTC and PTC thermistors.
