Dusk-to-Dawn Light
This was the first lab we actually got to do something that worked. Below, our circuit is drawn. We measured the maximum and minimum resistance of our photo-resistor and we used that for our calculations. Instead of a 10K resistor between the collector and the base, we found that a 1K resistor allowed our circuit to work. Otherwise, there was too much and our circuit would not work properly.
Also show, in the picture is our calculations for how much voltage we would expect to measure. To do this, we first found the current through the photo-resistor. These are the boxed answers.
At the very bottom, we wrote our V_measured.
Above is our circuit in action.
