What does a miliampere (mA) measure?

• A. One millionth of an ampere
• B. One thousandth of an ampere
• C. One hundredth of an ampere
• D. One tenth of an ampere

Answer: (B)

A milliampere (mA) is a unit of electric current that measures one thousandth of an ampere. This is a standard metric measurement used to quantify smaller amounts of electric current, frequently seen in various applications, including electrolysis and laser treatments within the beauty and medical fields. Using the metric prefix "milli," which denotes a factor of one-thousandth, it is clear that a milliampere is exactly equivalent to 0.001 amperes. Understanding this scale is essential in fields that rely on precise electrical measurements, as different procedures or devices will necessitate specific current levels to function safely and effectively.
