I performed a simple circuit experiment using three resistors. What formula do I use to find the measured potential difference (V) in this case?

Note: Uncertainty in resistance can be calculated by the following formula: OR = (OR OV ) + (OR 81 ) Here, R - total resistance = . For calculus-based students, calculate the uncertainty in each total resistance based on the uncertainties in current and voltage measurements. For algebra- based students, have your TA calculate this for you. . /. diff = 1 1, 118.8 - 1, 114.71 x 100 = 0. 34./ . 1 , 118.8 V= IR XMeasured potential difference (V) = SR = ( V)2 + ( I) 1.
