Question

Two resistors are to be combined to form an equivalent resistance of 1000 Ω. The resistors are taken from available stock on hand as acquired over the years. Readily available are two common resistors rated at 500 ± 50 Ω and two common resistors rated at 2000 ± 100 Ω. (a) Calculate the uncertainties for both combinations. (b) What combination of resistors (series or parallel) would provide the smaller uncertainty in an equivalent 1000 Ω resistance?

Answer 1

Answer:

Even though each of 2000 ohms resistor has twice the uncertainty of a 500 ohms resistor, the parallel circuit has half the uncertainty of the series circuit

Thus, the PARALLEL CIRCUIT would be more accurate
