Just a practice problem for Thevenin. This was before I knew how to properly do the Thevevin process Lab (Thevenin Process) This is how our circuit will look like on the bread board. This is out theratical part of the lab. Also know as our pre-lab. We did not get the exact answers Our resistor was pretty good. It was suppose to be 7.7k but we go 7.57. Pretty close for how off our other resistors were. How voltage drop of the 6.8k resistor was lack luster though. Summary For the most part we got good results in many parts of our lab. However, we could not get the right theatrical value. We would always be off by double or by half. It was semi-weird but we must have just been overlooking something. All in all it was a meh lab. That said I now under stand the process of Thevenin.

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...

Lab In this lab we are conforming that Michael is the best. But real talk this lab, like most labs we are conforming that the methods that we are learning in class on how to calculate voltages, currents, and resistors. The picture above is a simple resistor heavy circuit; which is good for use because with mesh analysis having majority resistor is fun and simple. We are measuring the current along this part of the setup. We are getting a negative do to the simple issue of thinking the current was going the opposite direction. Or we just connected the multi-meter wrong. We are just of course checking that the photo resistor works. This is the ideal waveform for the photocell I believe. Summary Mesh Analysis is the best type of analysis if you are looking for circuits. It is mostly a secondary method after you do an initial method. However this only works if you know each resistance on the circuit. During the lab we had very similar theatrical values a...

This is a simple example of nodal analysis. Though we are going to use this method often, it is not my favorite.  Here is the numerical expression of the same circuit. Lab (Nodal Analysis II) This is how our little breadboard setup. We were measuring the voltage drop of the resistors. I would give you the resistors but its not needed; due to the fact that you do not want them. This is just the measurement of the following resistor. The voltage drop was slightly more then our previous resistor. I guess I changed my mind and gave you the actual resistor values. 6.8K Ohms 2.2k Ohms Summary Our Pre-Lab corriesponed with our experimental. The official way to state it, is that after solving our theoretical values we were able to conform that if we use nodal analysis we are in fact getting the right values and not some garbage numbers.

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 group...

With this in house diagram we were suppose to determine what would happen if we closed a switch. We thought it would make A dimmer and B stay the same, but we were wrong. It in fact both stayed the same since each potential remained the same. We wrote down what would the correlation with resistance and an objects length, area and material make up of an object. This is the real world units of Ohms. But its not very useful.  We were tasked to find the hot and cold resistance of this circuit. We calculated the hot resistance then determined that the cold resistance had to be less. We just measured the real world resistance of this... resistor. Then we measures the resistance when we have a voltage through it. Here we looked at how to calculate how much nodes. branches, and loops there are in this circuit. Simple K-Law example Lab First time with wave form. It did not turn out well. Our...
