What process would you use to convert milliamps to amps?

1. Multiply by 1,000

2. Add 1,000

3. Divide by 1,000

4. Subtract 1,000

The correct answer is: Divide by 1,000

To convert milliamps (mA) to amps (A), the correct approach is to divide the number of milliamps by 1,000. This is based on the understanding that one amp is equal to 1,000 milliamps. Therefore, when you have a value in milliamps and need to express it in amps, you take the milliamps and divide by 1,000 to obtain the equivalent amp value. This conversion is crucial in various electrical and electronic applications to ensure that measurements and specifications are compatible and accurately understood. For example, if you had 2000 milliamps, dividing by 1,000 would give you 2 amps, which illustrates how this conversion works in practice.
