If your readings were made with an uncertainty of 1 mm. how much percent uncertainty would result for r_x in the following three situations? : x = 10cm x = 50 cm x = 95 cm what would you expect to happen if the 2 v from the power supply were to be increased to 6 v? was the sensitivity of the galvanometer a limiting factor in this experiment? if so, under what conditions? how do fluctuations in the voltage of the power supply affect the results in the wheatstone bridge experiment? consider fig. 4.1. if current flows through the galvanometer from c to d in which direction should the contact point be moved to achieve the balance condition. compare the resistance from the wheatstone bridge measurement and the direct measurement from the multimeter. do they agree? include the error analysis in your comparison.
