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 gigaampere (GA) is a unit of electric current equal to 10^9 amperes (one billion amperes). Gigaampere-level currents are theoretical and have no practical generation or control capability with current technology. The unit exists within the SI metric system framework for mathematical completeness. Gigaampere discussions appear only in theoretical physics and speculative discussions of extreme electrical phenomena or cosmic events.
