Question

write an equivalency statement relating amperes and milliamperes. reference \powers of ten\ by clicking on the \chemistry resources\ link at the top - left of the page.

• write a 1 in front of the larger unit
• determine the power of 10 for each prefix
• subtract the small power of 10 from the large power of 10

1 x 10<u> </u>-(-3)=<u> </u>

• write the power of 10 calculated above in front of the smaller unit. enter the number in standard scientific notation if the number is too large.
• make sure to enter the power into the blank in the \e\ form. for example, if your power is 10^5 enter 1e5 into the blank.
• write the larger unit on the left of the equal sign and smaller unit on the right.
• if you need the greek letter mu, copy and paste the symbol below
• μ

Explanation:

Step1: Identify prefix powers

The prefix "milli -" means $10^{- 3}$. The base unit ampere has a power of $10^{0}$.

Step2: Calculate power difference

We subtract the power of the prefix of the smaller unit from the power of the base (larger) unit. So, $0-(-3)=3$.

Answer:

$1\ A = 1\times10^{3}\ mA$
