Photo Resistor Lab

By -
Dusk to Dawn Light

There is our pre-lab work. We calculated the resistance for when the light hit the photocell and when light doesn't hit the photocell. We calculated around 12k resistance. It took a while to get the resistance because we cant do simple math.
I picked a 12K resistor from the bin but it was not exactly 12k when we measured it . 11.99k is pretty close; basically perfect, but not exact.

Here is the overview of our circuit setup. It shows how simple the circuit is.

Close up look of the circuit setup.


The voltage of the system when the room light was hitting the photocell.
It reads about 2.53V






 The voltage shoots up to 3.06V. This is pretty good when it comes to our lab. It beets the .5V delta that we needed to have ever so barley.

Summary

All in all we were extremely "bigly" successful in this lab. One of our voltages was on point and the other was not far away.  We checked with other groups and they got similar results though our math in the pre-lab had a few errors.


I always seem to be barely off when it comes to these type of equations. I get it but usually one sign is off.

We are just reviewing what we did in our lass class meeting. It was a simple mess problem. Why cant all problems be mess. He should only ask us to fin the current of a circuit and not the voltages. I did not really understand what he was doing here. You are suppose to assume that the voltage is a random number then solve for everything else on the circuit then when you get to the other voltage source you see the ration that you are off by then multiply everything else by it and then you will get your answer. Lab (Super Position II) I don't know how to rotate this picture, but it is our first example of superposition. We are suppose to find the currents at places with superposition even though mesh law is better for this situation. This is how we set up our "breadboard". We try to make it look like the white board setup to make it easier to read and determine what resistor We are just measuring the voltage drop on each resistor. With t...

Looking back to this day in lab made me wonder how it looked so hard before. We just had to follow some simple steps to find "a" and "w" . Then find s1 and s2 for the circuit This was a different problem but here we determined if the circuit was over damping, under damped or critically damped F ollowing that we found the ratio of a/w. LRC Lab I n the pre-lab we had to theoretically find how the circuit would react to the given conditions  I t was a simple circuit as seen about. We has to measure the response across the Cap and Inductor.  Conclusion  In the end the circuit acted the way that we thought I would in the pre-lab. The graph below shows the discharge of the capacitor (I think).

This was some want something I was able to do. It took  me a while to get back into my mojo. OH... here is Q and B. I did not know what that meant  on the final. Lab In the pre-lab we needed to figure out how the circuit would  respond in many different frequencies. In the end we got good data and everything was the way it was suppose to be. It took a long time to just get the numbers. it felt like busy work.
