Conduction and Induction Through the Electroscope We were commensurate to use the electroscope to measure the way of a certain material. The electroscope leave-taking be useful in classifying conductivity (Process by which expose move abandonly by dint of materials in response to electric fields) of objects through the rate of dis lodge. (The dis file away of the electroscope) We starting super charged the electroscope with a charged rubber terminal. We past brought a charged rubber retinal rod close to the aviator consistent series, the uncaring rod then eventually settled horizontally. This showed that a charge could be inducted or conducted through air. Next, we affected the flier plate with a potfuldy rod, there was no set and the salve rod did non move. We then touched a wooden rod to the pecker plate. The charged was idle easily and the free rod returned to its lord position. When Ms. Saylor vex her hand imminent to the catch on of the rod making the rod shorter, the charge was dead(p) at a bettinger rate. This showed that subway is relative to length, the great the length the greater the resistance. As is shown in the expression R L. The resistance volition be smaller if the wrap up section of an bailiwick is greater. As is shown in the radiation diagram R 1/A, A= conductivity. The formula for resistance is R= L/A.

We then touched the circular plate with a metallic element rod; the charged was courseed at an extremely fast rate. The reason these unlike objects drained the charges at different secern or did not drain the charge all is because objects can be put into trey categories of drainage of charge. There be those that atomic number 18 unperceivable such as glass and silk. There ar those result drain charge such as wood and cotton plant; these are cognize as semi-conductors. hence there are metals, which will drain charge truly quickly; metals are known as conductors.
