A milliamp is equal to how many amperes?

Explanation:
Milli- means one thousandth, so a milliampere is 1/1000 of an ampere. Since 1 A equals 1000 mA, 1 mA equals 0.001 A. That’s why the correct value is 0.001 A. The other options correspond to larger amounts of current: 0.01 A is 10 mA, 0.1 A is 100 mA, and 1 A is 1000 mA.
