Frequently Asked Questions

What is the difference between Ampere and Milliampere?
Ampere (A) is the SI base unit of electric current, while Milliampere (mA) is a subunit equal to one-thousandth of an ampere. 1 A = 1000 mA, and 1 mA = 0.001 A.

When would I use Microamperes vs Milliamperes?
Microamperes (µA) are used for very small currents like those in integrated circuits, sensor readings, or leakage currents. Milliamperes (mA) are used for moderate currents like those in LEDs, small motors, or consumer electronics. Amperes (A) are used for larger currents like those in household appliances or power systems.

What are Abamperes and Statamperes used for?
Abampere (abA) is the CGS electromagnetic unit of current, used in some theoretical physics contexts. Statampere (statA) is the CGS electrostatic unit of current. These are specialized units mainly used in academic and research settings.
