Day 10

In this lab, we are going to learn a knowledge, and find the relationship between Vin and Vout.

we measure two resistors R1 and R2. the R1 is 1.76k ohm, and the R2 is 3.49k ohm.

Experiment set up:

Every time, when we enter an Vin, we can find a Vout. Recording the data.

We enter the data into Excle, and use data to make a graph.

In the graph, we find the highest Vout is 4.0V, and lowest Vout is -3.5V  In fact, the value should be positive 5V to negative 5V. but depend it is quality, the answer is different.
