Unit Definitions
What is a Ampere (A)?
An Ampere (A) is the standard unit of electric current in the International System of Units (SI). It measures the flow of electric charge.
History
The unit is named after André-Marie Ampère, a French physicist who was one of the founders of the science of classical electromagnetism. The term was first used in the 19th century as a way to quantify electrical current.
Current Use
Today, Amperes are widely used in electrical engineering and electronics to specify the amount of current flowing through circuits, critical for designing safe and effective electrical systems.
What is a Milliampere (mA)?
A Milliampere (mA) is a derived metric unit of electric current equal to one thousandth of an Ampere.
History
The term milliampere came into use as electrical devices became more compact and required measurements in smaller units. It has been a standard measurement in electrical engineering since the early 20th century.
Current Use
Milliamperes are commonly used in low-power applications, such as in medical devices, mobile phones, and other electronics where precise measurements of current are necessary.
