A resistor of $6 k Ω$ with tolerance $10%$ and another resistance of $4 k Ω$ with tolerance $10%$ are connected in series. The tolerance of the combination is about

Options:

Answer:

Solution:

In series combination equivalent resistance, $R = R_{1} + R_{2} = 6 + 4 = 10 k Ω$ Error in combination, $Δ R = Δ R_{1} + Δ R_{2} = \frac{10}{100} \times 6 + \frac{10}{100} \times 4 = 0.6 + 0.4 = 1 \frac{Δ R}{R} = \frac{1}{10} = 10%$
