What is equivalent to one ampere?

  1. 100 mA

  2. 500 mA

  3. 1,000 mA

  4. 2,000 mA

The correct answer is: 1,000 mA

One ampere is equivalent to 1,000 milliamperes (mA). This equivalence is based on the metric system conversion where "milli" denotes a factor of one-thousandth. Therefore, when you convert amperes to milliamperes, you multiply the number of amperes by 1,000. In practical terms: - 1 ampere (A) = 1,000 milliamperes (mA). Thus, when evaluating the choices, 1,000 mA directly correlates to 1 A, making it the correct answer. The other options, such as 100 mA, 500 mA, and 2,000 mA, do not represent one ampere but rather lesser or greater amounts, which illustrates the importance of understanding metric prefixes in electrical measurements.
