Lab 2 Summary In this lab, the purpose was to understand how to use a DMM to measure different things like resistances, current, and voltages as well as how to successfully comprehend the electrostatic relationship between various objects. In the first part of our lab we learned how to use a Digital Multimeter by using a simulator to draw diagrams of circuits. This helped give us a basic understanding that when dealing with a circuit and tools like a DMM, you have to connect wires to certain places and make sure the positive is touching the positive side. In the second portion of the experiment, we learned how to use the equipment that will be used for the other labs. This was done by making a list of the DMM’s limitations and writing a

In the fourth part of the experiment, we measured the charge between two items after being rubbed together. This helped understand how and where positive and negative charges form between various wands and fabrics. For example, when felt was being rubbed with PVC the felt would attract the negative charges while the PVC attracted the positive charges. This observation was done using a program called LoggerPro and a measuring device called Faraday Pail. Although it was difficult to measure exactly how much of a positive or negative charge it had, you could clearly tell if the data colleting was going down in numbers or up. In the lat portion of the lab, we used our prior knowledge from the lab and applied it to the question asking what would happen if a charged ball touched an uncharged. It was hypothesized that since one ball is charged then the uncharged ball would become charged as soon as they come in contact but only half the amount. After conducting a few trials, we determined that the single charged ball had a charge of 1.175 nC at 3000 but when they came in contact, the initial ball had a charge of 0.69 nC while the second ball had a charge of 0.82 nC. In conclusion, this proved that when a charged ball touches an uncharged ball then the net charge will disperse almost evenly
