Electric Current
Electric current measures charge flow rate. Fundamental to all electrical systems. Ampere is SI base unit, with milliamps and kiloamps for different scales.
Current Basics
Electric current (I) in amperes (A). 1 A = 1 C/s (coulomb per second). Direction: conventional current flows positive to negative.
Practical Ranges
LED: 20 mA, Household outlet: 15 A max, Car starter: 200-400 A, Lightning: 30,000 A peak, Power transmission: 1000+ A.
AC vs. DC
AC current alternates direction (60 Hz in US, 50 Hz elsewhere). DC flows one direction. Different safety and design considerations.
Common Applications
Circuit design, fuse/breaker sizing, motor specifications, power system design, and safety analysis.
Conversion Tips
Household breakers: 15-20 A typical. Electric car charging: 30-100 A. Arc welding: 100-300 A. Always consider safety limits.
