At the start of class we did some problems
 |
We did some practice problems

 |
We did additional problems
|
Starting lab....
In this lab we analyzed summing of two voltage source will be amplified, basically, we are setting up a circuit that will sum the voltage of two sources and if we adjust as we desire, we can amplify those voltages.

| Setup(1) |
 |
| Setup(2) |
 |
| Setup(3) |
 |
| This is V_out for 1V and 2V sources, together they will have -(2+1)=-3 V |
 |
| We recorded actual resistance (The calculation we showed at left uses 1.3K-ohm as a resistor but in lab we used 2.2K-ohm resistor as our resistor. |
 |
| Our result |
Summary: In our result, we did get really similar to what we expected, with just minor difference. It is very likely to cause by actual resistance of resistors. We got negative number of sum of voltages. Additionally, the voltage is saturated at -3.35 Volt but we did not get upper limit saturation.
