Introduction
Milliamperes (mA), a fundamental unit of electrical current, measure the flow of electrical charge. Ranging from as low as 10 mA to as high as 100 mA, this current range holds immense significance in numerous applications. Understanding the versatility of milliamperes empowers us to harness their transformative potential across diverse industries.
Applications of Milliamperes
Electronics

Industrial
Power Consumption
The power (P) consumed by a device is determined by its voltage (V) and current (I): P = V * I. For a constant voltage, a higher current (e.g., 100 mA) will consume more power than a lower current (e.g., 10 mA).
Battery Life
In battery-powered devices, milliampere current draw directly impacts battery life. Higher current consumption depletes batteries faster than lower consumption. Optimizing milliampere requirements is crucial for extending battery life.
Emerging Applications
The increasing demand for efficient and portable devices is driving innovative applications for milliamperes:
Table 1: Typical Applications and Corresponding Milliampere Ranges
