Unit Information
Microampere
A metric subunit of electric current equal to one millionth of an ampere (10⁻⁶ A). Essential for microelectronics, integrated circuits, and ultra-low-power applications where minimal current consumption is critical. Used in precision instrumentation, semiconductor characterization, biomedical sensors, and energy-efficient devices. Particularly important in CMOS technology, memory circuits, and battery-powered IoT devices where leakage currents and standby power are measured in microamperes.
Milliampere
A metric subunit of electric current equal to one thousandth of an ampere (10⁻³ A). Widely used in electronics for measuring small currents in circuits, semiconductor devices, and low-power applications. Commonly employed in consumer electronics, medical devices, and sensor systems where precise current control is essential for proper operation and battery life optimization.
