1. The difference between measuring voltage and current using a DMM is that when you are measuring voltage you place the probes on the node where you want to know the voltage and the probes must be in parallel with the nodes.. When you measure current you need to break the circuit and then place the nodes on the two broken parts of the circuit. For measuring  current the probes must be in series with the nodes.

2. You can get three different voltage values from the power supply at one time. Two of these values can have their voltage changed between 1-24 volts. The third is always 5 volts.

3. We built a practice circuit in class, it is pictured below and there is a video of it as well.

4. To prove Ohm's law we used resistors that we measured the values of and then used the practice circuit above with 5 different know voltages`. We then measured the amperage of the circuit and using the equation V=IR we solved for the resistance to check that it was close to what we measured. A picture of our work is below.

5. The final project we worked on a set up for a Rube Goldberg project. Our circuit was powered by our power supply and used a light sensor. When a light was shined on the sensor it powered a motor. A video of our circuit is below.
