Electric current is the rate at which electric charge flows through a conductor. It is measured in amperes (A), the SI base unit named after French physicist André-Marie Ampère. One ampere equals one coulomb of charge passing a point per second (1 A = 1 C/s). Current can flow as direct current (DC)—in a single direction—or as alternating current (AC), which periodically reverses direction and powers most homes and businesses worldwide.

A statampere (statA) is a unit of electric current from the CGS electrostatic system. One statampere equals approximately 3.336 × 10^-10 amperes in SI units—significantly smaller than the SI ampere, reflecting the different electromagnetic conventions of the CGS system. The statampere developed as part of Gaussian CGS notation used in theoretical physics, particularly in older classical electromagnetism textbooks. The unit remains in some theoretical physics literature and historical scientific works, but SI units (amperes) are now universally standard in electrical engineering, instrumentation, and contemporary scientific practice. Modern researchers encounter statampere notation primarily when reviewing historical literature or studying classical field theory.

A kiloampere (kA) is a unit of electric current equal to 1,000 amperes. Kiloamperes appear in electrical power transmission systems, arc welding equipment, and industrial electrical installations. High-voltage power distribution systems carrying large amounts of electrical power use kiloampere-level currents. Lightning strikes deliver currents measured in tens of kiloamperes. Industrial facilities with large machinery, electrolysis equipment, and heavy electrical loads operate at kiloampere ranges. The kiloampere provides a practical scale for expressing the large currents found in industrial power systems and specialized equipment.
