Question: 1 / 400

How is one one thousandths of an ampere expressed?

Milliamperes

One one thousandth of an ampere is expressed as milliamperes. The prefix "milli-" denotes a factor of one thousandth (1/1000), so when we refer to milliamperes, we are discussing a thousandth of an ampere. This is commonly used in various applications, such as in electronics and electrical equipment, where smaller current measurements are frequently needed.

In contrast, the other options utilize different prefixes that represent other factors: "centi-" represents one hundredth (1/100), "micro-" represents one millionth (1/1,000,000), and "kilo-" represents one thousand (1,000). Understanding these prefixes is crucial for accurately interpreting and measuring electrical currents in different contexts.
