b) Suppose you put a constant current (I) through the 2 resistors from part a) Then you measure the total voltage (V) across the 2 resistors (total R). You measure this V three times using a digital voltmeter, yielding: 0.247 V, 0.24 V. and 0.251 V. For your three voltages, calculate the relative uncertainty in the mean value (standard error of the mean) for the power dissipated in R. Give your answer for this standard error of the mean in percent of the mean (average power); that way you do not need to know R
