Solderless Breadboards

Solderless Breadboards


This is the resistance i got when i connected the leads of the DMM to two holes in the same row. The value is .8 ohms which is really low. This operates as a short circuit. 





When we connected the two rows of hole son opposite sides of the central channel we noticed that we had a really high resistance, this is because the leads are separated from each other which causes an open circuit.



When we connected the leads in two arbitrary holes our DMM had a very large resistance, this is because again, the leads are isolated which causes an open circuit



When we connected the leads with a jumper wire between the nodes our DMM read a very low resistance. The reason for this is because this configuration causes a short circuit.

Difference Amplifier

 In the bottom right we provided the relationship between the output voltage and the input voltage. Which broke down to the output V is equal to R2/R1*(Vb-Va). It's called a difference amplifier because it amplifies the difference between the two V sources and rejects the common signal between the two. Here is a schematic of the circuit we made. The actual resistances of the resistors are on the previous pic. Which were R1=R3=9.7 kOhm, and R2=R4=19.9 kOhm Here's a table of our output and input voltages. Our graph sort of worked out. It roughly resembles a proper saturation graph  This one however is completely off. fe Here are our values in excel with error. When Vb=1 i expected the saturation to be around 4.30 and -4.6, since our values topped off around there. However, when Vb=-1 we got max 5.24 and -3.6. So there must've been a mistake with our circuit. However, some values did make sense. For example, when Vb=1 our valu...

Summing Amplifier

 Here is a pic of our pre lab, we chose 22kOhms for our resistors. The actual values however were, R1=21.5kOhm, R2=21.7kOhm R3=21.4kOhm. Since our R values should betheoretically equal, our Vout equation should be Vout=-(Va+Vb). Our values made since except for Va=1, the value should've been -1V but it was -1.94V. For the last two values the %error was huge because of the saturation of the Op-Amp. Here are our experimental values from our board  Here's our circuit
