About Electric Current
Electric current is the flow of electric charge through a conductor. Electric current is measured in amperes (A) where one ampere is one coulomb of charge passing a point in one second.
- Ampere (A) - SI unit for electric current.
- Milliampere (mA) - One-thousandth of an ampere (10⁻³ A).
- Microampere (μA) - One-millionth of an ampere (10⁻⁶ A).
- Nanoampere (nA) - One-billionth of an ampere (10⁻⁹ A).
- Picoampere (pA) - One-trillionth of an ampere (10⁻¹² A).
- Kiloampere (kA) - One thousand amperes (10³ A).
- Megaampere (MA) - One million amperes (10⁶ A).
- Abampere (abA) - CGS electromagnetic unit (1 abA = 10 A).
- Statampere (statA) - CGS electrostatic unit (1 statA ≈ 3.33564×10⁻¹⁰ A).
Current Units
Electric current is the flow of electric charge in a conductor, and its measurement is the focus of electronics, physics, and electrical engineering. Many units characterize current in terms of magnitude and context.
- Ampere (A): The SI base unit of electric current, representing the flow of one coulomb of charge per second. It is the base unit for most theoretical and practical applications.
- Milliampere (mA), Microampere (μA), Nanoampere (nA), Picoampere (pA): Units used in precise electronic measurement and instrumentation to measure small currents with accuracy.
- Kiloampere (kA), Megaampere (MA): Units for very large currents, used in high-power electrical systems, industrial equipment, and plasma physics.
- Abampere (abA): A historical unit from the CGS electromagnetic system.
- Statampere (statA): A unit from the electrostatic unit system, less common today but still used in some theoretical and specialist applications.
All in all, the current units provide a full set to express electric current on any scale and across any science.
