INTRO: Today we did some review of what we had already learned and applied it to some more practical circuit building. We also built a new circuit which incorporates new types of resistors.
Below we are given a circuit and asked to evaluate it. We used a concept like Nodal analysis to evaluate the circuit and express terms in other circuit terms.
In today;s lab we design a circuit with an output voltage which provides a temperature measurement. We used a thermistor which is a device that changes with temperature. By holding the thermistor, it would get hotter, which would increase it's resistence.
In the pre-lab, we calculated some measurement of resistance within the circuit
Below is a picture of our setup for the circuit. At the top the symbol with the resistor and an arrow through it signifies a variable resistor, which is what the thermistor is.
Here is our setup of our diagram.
Below are our results for the lab.
Here we calculated the percent error in our experiment.
