Question

A resistor of 10 k Ω having tolerance 10% is connected in series with another resistor of 10 k Ω having tolerance 10%. The tolerance of the combination will be(a) 10%(b) 13%(c) 30%(d) 20%

Answer 1

$opt \: c) \: 30\%$

$r1 = 10k \: and \: tolerance \: is \: 10\% \\ 10k \: = 10000 \: ohms \\ 10\%of \: 10k \: = 1000 \: ohm \: r1 \: min \: = 10000 - 1000 = 9000. \\ hope \: it \: helps \:$
