Day 10: Inverting Voltage Amplifier

This is the inverting op amp circuit. By changing the voltage in and measure the effects of the op amp. so that the saturation can be seen as well as the voltage that seeps in from the source when the voltage input is zero.

This is the break down of the Op Amp as though it where two seperate components that are just proportionally reliant on each other. The voltage across the resistor and the voltage from the source. Gosh there is so much stuff going on here, It hurts to look at the day before the celebration.

This is the circuit itself using the Op Amp. You can see the source supplied and and the oscilloscope measuring the resistance. I hope there are not any questions about how to use waveform, I would be in trouble. Time to sleep so I have energy to Celebrate tomorrow.!!!!! CELEBRATE GOOD TIMES COME ON!!!!

Day 9: Maximum Power Transfer and Non-Ideal Power Source

This is showing that the resistance that creates the maximum power is when the resistance in the thevenin circuit is equal to that of the thevenin resistance.

This is calculating max power in a circuit.

This is the prelab is used to set up the equations required to calculate the resistance due to the voltage source coming from the analog discovery. it uses a system of equations to measure the adjustment to the system brought on by the voltage source making sure that in one situation it is equal to zero and then changing the resistor.

This is the circuit using the wavefunction to generate a voltage and measure the current. and to measure the resistance inside of the analog discovery.

Day 8: Thevenin's Theorem

This circuit is simplified to measure the one resistance and the one voltage so that as you change one resistance it is easier to calculate its effects on the system.

This is all the work, measuring all the components so that theoretical and experimental can be seen simultaneously. The thevenin resistance and thevenin voltage effects as one resistor is changed and how the voltage across it will change accordingly.

This is everycircuit, it should the current and voltage throughout a theoretical circuit. 

This is the circuit that is used for the experiment using a potentiometer to change the resistance.

This is the thevenin circuit.

Day 7: Time Varying Signals

This is the set up for a BJT curve tracer. It contains two voltages that vary differently as they have different effects on each other as they travel through the BJT.

This is the effects of a change in the resistance on the circuit. The wavelength is constant but the amplitude is decreased.

This is a closer look at the BJT Curve Tracer set up. It has one voltage source that is DC and the other is a step voltage source.

This is the set up of the circuit. The graph is what is expected to see from the voltage out of the transistor.

This the view of the voltage coming from the waveform and the oscilloscope measuring the output.

Using a triangle voltage supplied from the wave form, the oscilloscope measures a triangular wave output.

This waveform uses a sinusoidal wave.  The oscilloscope measures a sinusoidal wave.

This is the graph as the voltage is stepped up and it reaches its limit across the transistor.

Day 6: Nodal Analysis III

Even though this lab is called Nodal Analysis. I am doing Mesh Analysis. Cause I am my own boss.

This is a super Mesh, in which the current source is removed. It would be really crazy if there was a question on the celebration tomorrow that required a source conversion and then a super mesh or a super node. I am ready. 

This circuit contains three full loops that cover each of the circuit components in the smallest loops possible.

The voltage drop is measure across a resistor.

Every piece of the circuit is analyzed. This has a theoretical voltage across the resistor and then the measure voltage across the resistor in order to create a percentage uncertainty.

Day 5: Nodal Analysis

This is an example of nodal analysis. Using I=V/R and looking at currents coming and leaving at a node to calculate voltages as the current is conserved.

This is a circuit using three resistors and measuring voltage.

This circuit allows for the measurement of the voltage at the node 2 using nodal analysis and then measuring the value and using % error as theoretical versus experimental.

Day 4: Temperature Measurement System

This is just a sample circuit calculating the voltage across a resistor from given two current sources. This would be a lot easier if I had known source conversions...

This video shows the heat actually decreasing the resistance and increasing the voltage drop across the resistor. 

This is the equation showing how as the resistance changes, the ratio of the two resistors changes and has a direct effect on the voltage drop across the other resistor. By running the experiment multiple times using different resistors to measure across then the requirement of getting a 0.5 voltage change by using a greater resistant.

Day 3 : Bipolar Junction Transistors (BJTs)

The first rule of hot dog cooking club is to not get cheap hot dogs that smell like hair when they are cooked.

In order to get a thoroughly cooked dog, Make sure you us a large voltage source.

This is what circuits in the future will look like. Actually it is LEDs plugged in across the hot dog in different orientations relative to the dog. Only the ones that are lined up parallel to the dog and in the correct direction light up.

This is a voltage source and a capacitor. A graph of the voltage from the capacitor when it is supplied with a square wave.

It is important to be comfortable when you analyze circuits. This is a voltage do-hickus which changes the voltage across the second resistor by adjusting the ratio  of the resistors it has a proportional effect on the voltage across the resistor.

This is a circuit conversion to create a more simple circuit that can be easily analyzed for the adjustments in one resistor.

There is a photo-resistor in this circuit which decreases the resistance in the system so that the LED receives a higher current when it gets dark.

This is the circuit using the photo-resistor.

This is the circuit of how the photo-resistor changes the drain current on the supply allowing more current to flow through the transistor and into the LED, Using a Light Dependent Resistor and a Bipolar Junction Transistor.

matrix laboratory

This is just simple input steps on free mat.

This is designating variables.

Creating Matrices.

Multiplying Matrices.

Outputting individual rows and columns.

Printing out sinusoidal functions.

This is an attempt at getting the program to create a file and access it. It gave me an error and then questioned my authority as admin.

No one questions my authority. This program cross the line and so I handled it. It still wont access the functions I save. Freemat 1: MikE 0

Day 2: We did a lot of stuff on this day.

This is a simple circuit experiment understanding if connecting this circuit will change the brightness of the light.

The lights stayed the same and the middle light did not light up. That is not the middle light you see there.

These are graphs that relationships between voltage and current that can and cannot exist. The ones on the right are labeled A, which could be a diode, and B, which is impossible.

This is the Analog Discovery. It has been compared to Thor's Hammer, to the scientist that made the Steve Austin, and if it were a heat engine it would be have a 31% rating for efficiency.

This is just the measurement of the resistor before an experiment was done to measure the change in current as the voltage is adjusted.

This is all the data collected using the RC.

This is the circuit that the experiment used.

This is the graph of change of current over voltage. They have a linear relationship in this circuit, because it only consists of a resistor and a voltage source.

This is an equation to calculate the number of components from the number of independent circuits and nodes.

This is the use of KVL to calculate the current and the voltage across a point.

This circuit has a resistor and a transistor. This is a MOSFET or a metal oxide semiconductor field effect transistor. this is an n-channel. It consists of a source a drain and a gate. The power supply is connected to the drain  and it allows current to flow from the drain to the source, 

This is a diagram of the circuit that was created for the experiment. It also contains the values of the voltage supplied by the analog discovery and the measure current.

This is showing the change in the bulb if another voltage source is brought in parallel to one of the bulbs.

These are both wrong because the voltage source in parallel so neither of the bulbs change.
