About the Electric Current Converter
Electric current is the rate of flow of electric charge through a conductor, measured in amperes (A) — one of the seven SI base units. One ampere equals one coulomb of charge flowing per second. Electronics typically operate in milliamperes (mA) and microamperes (μA), while power transmission lines carry kiloamperes (kA). Current direction conventions differ: conventional current flows positive to negative, while electrons move in the opposite direction.
Quick facts
- ›The human body can feel currents as low as 1 mA; currents above 100 mA can be lethal
- ›A typical smartphone charges at 1–3 amperes; fast chargers can reach 6–12 A
- ›Lightning bolts carry currents of 1,000–300,000 amperes lasting microseconds
- ›The ampere is defined by fixing the elementary charge at exactly 1.602 × 10⁻¹⁹ coulombs
