20 milliamperes is equivalent to which of the following?

To determine the equivalent value of 20 milliamperes (mA) in amperes (A), it's essential to understand the relationship between the two units. Milliamperes are a subunit of amperes, where 1 ampere equals 1,000 milliamperes. Thus, to convert milliamperes to amperes, you divide the number of milliamperes by 1,000.

In this case, converting 20 mA to amperes involves the calculation:

20 mA ÷ 1,000 = 0.02 A.

This conversion reveals that 20 milliamperes is equal to 0.02 amperes.

Consequently, this understanding confirms that the correct answer is indeed the conversion that matches this result, making the value of 0.02 amperes accurate for the given question.
