MCQ (Single Correct Answer)

-0.3

Two resistors with nominal resistance values $${R_1}$$ and $${R_2}$$ have additive uncertainties $$\Delta {R_1}$$ and $$\Delta {R_2},$$ respectively. When these resistances are connected in parallel, the standard deviation of the error in the equivalent resistance $$R$$ is

$$ \pm \sqrt {{{\left( {{{\partial R} \over {\partial {R_1}}}\Delta {R_1}} \right)}^2} + {{\left( {{{\partial R} \over {\partial {R_2}}}\Delta {R_2}} \right)}^2}} $$

$$ \pm \sqrt {{{\left( {{{\partial R} \over {\partial {R_2}}}\Delta {R_1}} \right)}^2} + {{\left( {{{\partial R} \over {\partial {R_1}}}\Delta {R_2}} \right)}^2}} $$

$$ \pm \sqrt {{{\left( {{{\partial R} \over {\partial {R_1}}}} \right)}^2}\Delta {R_2} + {{\left( {{{\partial R} \over {\partial {R_2}}}} \right)}^2}\Delta {R_1}} $$

$$ \pm \sqrt {{{\left( {{{\partial R} \over {\partial {R_1}}}} \right)}^2}\Delta {R_1} + {{\left( {{{\partial R} \over {\partial {R_2}}}} \right)}^2}\Delta {R_2}} $$
