Question

A technician has 10 resistors each of resistance $0.1\Omega$. The largest and smallest resistance that he can obtain by combining these resistors are:

• A. $10\Omega$ and $1\Omega resp.$
• B. $1\Omega$ and $0.1\Omega resp.$
• C. $1\Omega$ and 0.01 resp
• D. $0.1\Omega$ and $0.001\Omega resp$

Answer 1

Answer: (C)

$1\Omega$ and 0.01 resp

$R_S=10\times 0.1=1\Omega \left(largest\right)$
$R_P=\frac{0.1}{10}=0.01\Omega \left(smallest\right)$
