2. Consider a parallel network of 3 resistors in parallel (recall back to physics class). The combined resistance of these three individual resistors can be calculated using this expression: R1 R3 1 Root R Where: R, = 220 0 + 1%, R, = 72012 + 1%, and R. = 2000 0 + 1%. Calculate the total resistance of this parallel resistor network, Rot, and its associated uncertainty, ORtor, given the above manufacturer-provided data. Show all your work.2.
