If you place resistors of values 38.3±3.8Ω , 27.7±2.8Ω , and
22.5±2.3Ω in series, what is the equivalent resistance and the
absolute accuracy of the equivalent
resistance?
Accuracy x + Ax Ax is the absolute accuracy measurand accuracy of measurand Propagation of Accuracy for calculated values C is the calculated value and AC is the absolute accuracy of the calculated value Addition/Subtraction C = x₁ ± x₂ ± ... C = X₁ X₂ X3... Or Multiplication/Division C = x₁ + x₂ + x3 + ... Or mixed C = X₁ X₂ X3... Squares C = x₁(x₂)²(x₂)³.... 4x is the relative accuracy X (usually expressed as a percentage by multiplying by 100%) AC = √(Ax₂)² + (Ax₂)² + ... add absolute accuracy in quadrature 2 AC Ax₁ = + + + *** C add relative accuracy in quadrature 2 2 2 AC +4 +9 + www C X2 X3 add relative accuracy in quadrature weighted by exponent
22.5±2.3Ω in series, what is the equivalent resistance and the
absolute accuracy of the equivalent
resistance?
