Question

The smallest resistance that can be obtained by combining 10 resistors each of resistance 10 $\Omega$ is

• A. $10\Omega$
• B. $0.5\Omega$
• C. $2\Omega$
• D. $20\Omega$
• E. $1\Omega$

Answer 1

Answer: (E)

When we add all resistors in parallel, the effective value will be the smallest.
$R=\frac{10}{10}=1\Omega$
