One milliamperes is equal to _____.

One milliamperes is equal to _____.

• A. 1/1,000 of an amp
• B. 1/100 of an amp
• C. 1/10 of an amp
• D. 1/1,000,000 of an amp

Answer: (A)

One milliamperes is equal to 1/1,000 of an amp. The milli- prefix in the metric system denotes a factor of one-thousandth (1/1,000). Therefore, when you see the term milliamperes (mA), it indicates that for every milliampere, you have 0.001 amperes. This conversion is fundamental in electrical applications, especially in HVACR, where precise measurements of current are crucial for ensuring system efficiency and safety. Understanding these metric prefixes helps in interpreting current flow and applying correct values when working with electrical components and circuits.
