Feb 15, 2015  An electric current (I) is the flow of electric charge from one place to another. Units: Coulomb per second (Cs) Ampere (A) Current in a directcurrent circuit always flows in the same direction, while current in an alternatingcurrent circuit periodically reverses the direction (this chapter only deals with DC, and chapter 24 will deal
