Current is defined the amount of Charge moving through a point per second. Conventionally, current is visualised as flowing from a point of high Electrical Potential to a lower Electrical Potential. A lot of things change when charge is moving, as we no longer treat them as static charges.

Definition

Given a cross sectional area, the current flowing through said area is given by:

Formula

Current

Terms
  • = Current (in Amperes, )
  • = Charge (in )
  • = Time period (in )
