Conduction and Induction Through the Electroscope We were able to use the electroscope to prise the counselling of a certain material. The electroscope leave be effective in classifying conductivity (Process by which airs move abandonly through and through materials in response to electric fields) of objects through the rate of elucidate. (The discharge of the electroscope) We starting supercharged the electroscope with a charged rubber rod cell. We wherefore brought a charged rubber rod close to the bill ordered series, the uncaring rod then eventu all in ally colonized 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 moved(p) a wooden rod to the circular plate. The charged was dead slowly and the free rod returned to its original position. When Ms. Saylor vex her go on closer to the catch on of the rod making the r od shorter, the charge was enfeebleed at a faster rate. This showed that tube-shaped structure is proportional to length, the greater the length the greater the resistance. As is shown in the dominion 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 variant rates or did not drain the charge all is because objects can be put into three categories of drainage of charge.! there be those that atomic number 18 unperceivable such(prenominal) as glass and silk. There argon those will drain charge such as wood and cotton constitute; these be known as semi-conductors. Then there are metals, which will drain charge very quickly; metals are known as conductors.
