25 amperes is equivalent to how many milliamperes?

To convert amperes (A) to milliamperes (mA), it is important to understand the relationship between the two units. One ampere is equal to 1,000 milliamperes. Therefore, when converting 25 amperes to milliamperes, you multiply by 1,000.

When you perform the calculation:

25 A × 1,000 mA/A = 25,000 mA.

This shows that 25 amperes is equivalent to 25,000 milliamperes, making this option correct. Understanding this conversion is crucial in electrical work, as it allows for accurate readings and ensures proper calculations are made when working with different units in an electrical context.
