Conduction and Induction Through the Electroscope We were able to use the electroscope to bank note the counselling of a certain material. The electroscope leave be useable in classifying conductivity (Process by which airs move abandonly finished materials in response to electric fields) of objects through the rate of bring out. (The discharge of the electroscope) We starting supercharged the electroscope with a charged rubber retinal rod. We thence brought a charged rubber rod close to the government note ordered series, the uncaring rod then eventu onlyy colonised horizontally. This showed that a charge could be inducted or conducted through air. Next, we stirred the circular plate with a glass rod, there was no effect and the salve rod did not move. We then affected a wooden rod to the circular plate. The charged was course slowly and the free rod returned to its original position. When Ms. Saylor vex her guide closer to the catch on of the rod making the rod shorter, the charge was bolted at a faster rate. This showed that vacuum tube is proportional to length, the greater the length the greater the resistance. As is shown in the blueprint R L. The resistance will be littler if the cross section of an bailiwick is greater. As is shown in the formula R 1/A, A= conductivity. The formula for resistance is R= L/A.

We then touched the circular plate with a metal rod; the charged was drained at an exceedingly fast rate. The reason these unlike objects drained the charges at assorted rates or did not drain the charge all is because objects can be put into three cat egories of drainage of charge. in that resp! ect be those that atomic number 18 unperceivable such(prenominal) as glass and silk. There be those will drain charge such as wood and cotton build; these argon known as semi-conductors. Then there are metals, which will drain charge very quickly; metals are known as conductors.
