Question

Two resistors are to be combined to form an equivalent resistance of 1000 ohms. Readily available are two common resistors rated at 500±50 Ω and two common resistors rated at 2000 ±5% ohm. Calculate the total uncertainty in ohms for (a) Series combination of 500 ohm resistances (b) Parallel combination of 2000 ohm resistances. Assume given uncertainties are related to 95% confidence level.
