Unformatted text preview: Physics Lab 9 Current Balance Joshua Budhu Lab Partner: Andrew Nouri Date Performed: 4/15/09 Date Due: 4/22/09 1 Objective and Theory For this lab, our objective was to essentially measure the amount of force that it took to generate the same force as a varying array of masses. The objective of this lab is to calculate by using a known voltage, cross-sectional area, and separation distance from plates. We use a laser beam and the constant force of gravity in order to ensure that we know the correct force that this specific voltage is exerting on the capacitor plates. The theory behind all of this involved Coulombs law, with the force equal to the charges, which in this case was currents, and the distance. 2 Set-Up 3 Data 100mg 150mg 200mg 250mg 300mg a 7mm 6mm 5mm 4mm 3mm I 4.51 A 5.45 A 6.39 A 7.52 A 8.44 A For our calculations we used the formula that was described in class. By using a systems of equations approach we were able to get an average value for b and we were able to...
