Understanding Electrical Current: Measurement and Definition
1C - Electrical current is measured as the amount of electrons passing through a medium in a given moment of time. It's measured in Amperes or Amps (A). The original definition of an Ampere was based on a unit called dynes. A dyne is the force needed to accelerate one gram at one cm/s squared. Two dynes per cm of wire length is the force between two wires a cm apart carrying 10 Amps.
