Effects of Electricity essays

Effects of Electricity essays In this lab, the effects of electricity were studied. This was done by observing the effect on a strip of metal foil when a charged rod was brought closer to it and by completing other similar experiments. These other experiments included examining the charge on common scotch tape and the various ways to give a rod charges. In the first experiment, a piece of tape was peeled off of the table and held close to some bits of tape, which it attracted. This showed that simply by removing the tape from the table, the tape became charged enough to attract the paper. Next, two pieces of tape were stuck to the table and when they were held together they repelled. The repulsion got stronger the closer together the pieces were held. Then, a piece of tape was hung off the edge of the table. A second was stuck on the table and a third was stuck on top of it. They were pulled from the table together and the peeled apart. When the bottom piece was brought close to the hanging tape, it repelled it. This shows that two pieces of tape, peeled from the same table, will share like charges, and thus repel each other. Next a series of experiments were completed using an ebonite rod, a glass rod, wool, silk, and an electroscope. In the first experiment, the ebonite rod was charged by rubbing it on wool and brought close to the hanging tape, which it repelled. This shows that the charge from the wool would easily transfer to the ebonite rod, and then share the same charge as the table and the tape. Next, the glass rod was charged with the silk and when brought close to the hanging tape it attracted it but when it was brought close to the straw in the electroscope, it repelled it, which shows that the tape shared the same charge, but the straw held an opposite charge. Then, the electroscope was neutralized with a finger and the charged ebonite rod was brought near the plate and the opposite side of the plate was touched with the finger...
