Question

The values of $mA$and $\mu A$are ___ respectively.

• A. ${10}^{-6}$ and ${10}^{-9}$
• B. ${10}^{-3}$ and ${10}^{-6}$
• C. ${10}^{-3}$ and ${10}^{-9}$
• D. ${10}^{-6}$ and ${10}^{-3}$

Answer 1

The correct option is B

${10}^{-3}$ and ${10}^{-6}$

Explanation for correct option: In case of option B, $mA$ means ${10}^{-3}$ and $\mu A$ means ${10}^{-6}$ is given.

$mA$ means milli-ampere. All the units with prefix “milli” are to be multiplied by ${10}^{-3}$.

$\mu A$ means micro-ampere. All the units with prefix “micro” are to be multiplied by ${10}^{-6}$.

So, option B is the correct answer.
