Anh Le PHY-1054 Professor McNutt Lab 1 Report: Electric Charge Introduction: The objective of this lab is to investigate the characteristics of electric charge and the effect of it on different materials. Theory: The frictional charging process results in a transfer of electrons between the two objects that are rubbed together. For example, rubber has a much greater attraction for electrons than animal fur. As a result, the atoms of rubber pull electrons from the atoms of animal fur, leaving both objects with an imbalance of charge. The rubber balloon has an excess of electrons and the animal fur has a shortage of electrons. Having an excess of electrons, the rubber balloon is charged negatively. Similarly, the shortage of electrons on the animal fur leaves it with a positive charge. The two objects have become charged with opposite types of charges as a result of the transfer of electrons from the least electron-loving material to the most electron-loving material. After rubbing the rod with fur or silk, the rods were given charges. When placing the charged rods close to each other without touching, they would either attract or repel on each other. Setting up the system with Faraday cage and the charge sensor and connect to the Xplorer GXL,
