Thevenin's Theorem

By calculating our equivalent resistance we were able to simplify circuits into one resistor and one voltage source

FreeMat

Temperature dependent voltage

We worked on the lab with a temperature dependent resistor, after setting it up, the voltage changed when we applied heat from our fingers. The temperature change from 20 degrees to 37 degrees proved to change the voltage

Night light

we used a photo sensitive cell that created more resistance when not exposed to light. this activated our led light and created light when it was dark.

Mosfets

On 2/26 we did an experiment involving mosfets
mosfet channel will only open after a certain threshold is achieved.
Once this threshold is achieved the energy peaks and plataus at a point and gives steady energy.
By using the skills we learned last lab we were able to find this threshold at around 1.5 v, peaking around at 2.2 V
