Question

A resistor of 6 kΩ with tolerance 10 % and another resistance of 4 kΩ with tolerance 10 % are connected in series. The tolerance of the combination is about, 5%, 10%, 12%, 15%

In series combination R = R 1 + R 2 = 6 + 4 = 10 k Ω Error in combination, Δ R = Δ R 1 + Δ R 2 = 10 100 × 6 + 10 100 × 4 = 0.6 + 0.4 = 1 Δ R R = 1 10 = 10 %
