Unformatted text preview: EXPERIMENT EC4 WHEATSTONE BRIDGE VI - 1 I then tabulated the data obtained in the following chart. = 50 L = 0.25 cm # L (cm) Rx () Rm () Rx () Rx () 1 21.70 78.30 0.25 180.41 174.51 2.65 5.90 2 35.50 64.50 0.25 90.85 87.39 0.99 3.46 3 48.30 51.70 0.25 53.52 51.59 0.54 1.93 4 67.90 32.10 0.25 23.64 23.02 0.27 0.62 A number of reasons could account for this. VI - 2 In the first experiment, we set up the apparatus as described using a given unknown resistance, and moved the slider along the resistance wire until we obtained a zero reading on the galvanometer. We then repeated the experiment for three other unknown resistances. We measured the value of L 1 , the distance from one side of the resistance wire to the position of the slider at the zero reading, and calculated the distance L 2 , the distance from the other side of the resistance wire. I also calculated the value of Rx, the error in R x and the value of Rx , the difference in the resistance obtained by the two methods.Rx , the difference in the resistance obtained by the two methods....
