The Vfinal is the similar to the sum of Vblue and Vwhite since the net charge of an isolated system remained constant.VI-3# Vinsert (Volts) Vground (Volts) Vwithdr (Volts) Vfinal (Volts)1 6.6 0.1 -6.4 0.32 0.9 0.1 -0.8 0.23 1.5 0.1 -1.2 0.4Diagrams of charge distribution for different situations are drawn on the paper at the back of the lab reportVI-4# of transfersnvoltage (volts)5 0.45 -4.25 -8.25 -5.610 0.110 5.510 810 5.815 0.115 -115 -2.115 -1.220 0.420 0.320 -2.320 -125 0.425 0.325 -2.325 -10 5 10 15 20 25 30-10-8-6-4-20246810f(x) = 0.04 x − 0.98V vs. number of charge transfers # of charge transfers Pail voltage (V)# of transfersnvoltage (volts)5 05 05 05 010 010 010 010 015 015 015 015 020 020 020 020 025 025 025 025 00 5 10 15 20 25 3000.10.20.30.40.50.60.70.80.91f(x) = 0V vs. n# of charge transfersShield voltage
