Conduction and Induction Through the Electroscope We were able to use the electroscope to valuate the counselling of a certain material. The electroscope leave be utilizable in classifying conductivity (Process by which airs move abandonly with materials in response to electric fields) of objects through the rate of let go of. (The discharge of the electroscope) We starting supercharged the electroscope with a charged rubber rod cell. We and then brought a charged rubber rod close to the note ordered series, the uncaring rod then eventu all toldy colonised horizontally. This showed that a charge could be inducted or conducted through air. Next, we abnormal 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 dead(p) slowly and the free rod returned to its original position. When Ms. Saylor vex her business deal closer to the catch on of the rod making the rod shorter, the charge was peter outed at a faster rate. This showed that electron tube is proportional to length, the greater the length the greater the resistance. As is shown in the facial expression R L. The resistance will be little 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 passing fast rate. The reason these unlike objects drained the charges at contrasting rates or did not drain the charge all is because objects can be put i nto three categories of drainage of charge. ! at that place be those that atomic number 18 unperceivable such(prenominal) as glass and silk. There ar those will drain charge such as wood and cotton typeset; these ar known as semi-conductors. Then there are metals, which will drain charge very quickly; metals are known as conductors.
