"Microamperes" Natural Recordings by Native Speakers
Microamperes refers to extremely small amounts of electric current, typically measured in units of one millionth of an ampere (1 μA or 0.000001 A). In other words, microamperes are tiny, very small electrical currents.
Microaggregates refer to small clusters or aggregates of particles, typically in the range of 0.1-100 micrometers in size, that are found in soil, sediments, or other natural environments.
Microalloyed refers to a type of steel that has been made by adding small amounts of additional elements, called "alloying elements", to the steel during its production process. The main purpose of microalloying is to improve the strength, toughness, and formability of the steel without sacrificing its weldability or machinability.
