How is 12mA equivalent to in Amperes?

To understand the conversion from milliamperes (mA) to amperes (A), it's important to know the relationship between these two units of electrical current. One ampere is equal to 1,000 milliamperes. Therefore, to convert milliamperes to amperes, you divide the number of milliamperes by 1,000.

In this case, to find out how 12 mA relates to amperes, you would perform the following calculation:

12 mA ÷ 1,000 = 0.012 A

This means that 12 mA is equivalent to 0.012 A. Thus, if we want to express this quantity in terms of whole numbers, moving the decimal point over three places to the left indicates that 0.012 A can also be considered as 12 mA.

The correct choice is not 1.2A, which would suggest a misunderstanding of the conversion factor. Each of the other choices involves much greater numbers and thus does not accurately represent the conversion of 12 mA. In summary, 12 mA is correctly converted to 0.012 A, and recognizing this conversion is crucial when working with electronic access control systems and understanding their
