milliampeerien

Milliampeerien, often abbreviated as mA, is a unit of electric current. It is derived from the base unit of electric current, the ampere (A), by dividing it by one thousand. Therefore, one milliampere is equal to 0.001 amperes.

The ampere represents the flow of one coulomb of electric charge per second. Since the milliampere is one-thousandth of an ampere, it measures a smaller, more granular flow of electric current. This unit is commonly used in electronics and electrical engineering to express the current drawn by devices or the current flowing through circuits, especially when the currents are relatively low. For instance, many electronic components like LEDs, sensors, and microcontrollers operate within the milliampere range.

The prefix "milli-" signifies a factor of 10^-3, meaning one-thousandth. So, 1 mA = 10^-3 A. Conversely, 1 ampere is equal to 1000 milliamperes. This relationship is crucial for understanding and calculating electrical quantities in various applications, from battery life estimations to the power consumption of small electronic gadgets.
