Day 8 (Thevenin lab)

Honestly if I invented something I would name it after myself too. The Carlos Munoz particle or maybe the Munoz technique. Anyway the class started by learning about the Thevenin theorem, which is extremely useful when you are unsure what kind of element will be added to your already complicated circuit and want a way to easily and quickly calculate how this new element will interact with your circuit. We first built this circuit in everycircuit and then we source transformed it to find its equivalent voltage and resistance across some unknown resistance. We found its thevenin voltage to be 30 volts and the thevenin resistance to be 4 ohms.

We did this again on a separate circuit seen here. The thevenin voltage and resistance was 40 volts and 20 ohms.

The lab Thevenin's theorem was a physical check to make sure that the theorem held true. In our pre-lab we determined that the thevenin resistance was 7.4 kiloohms and the thevenin voltage was .45 volts.
 

Here are pictures of the circuit that we built and the values that we obtained across the circuit.
