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

Options:

Answer:

Solution:

In series combination

$R = R_{1} + R_{2}$

$= 6 + 4 = 10 k Ω$

Error in combination,

$Δ R = Δ R_{1} + Δ R_{2}$

$= \frac{10}{100} \times 6 + \frac{10}{100} \times 4$

$= 0.6 + 0.4 = 1$

$\frac{Δ R}{R} = \frac{1}{10}$

$= 10 %$
