3 213 Energy and Power in Electric Circuits When a charge moves across a potential difference, its potential energy changes: Therefore, the power it takes to do this isCH21. pdf Chapter 21 Electric Current and Direct Current Circuits Section 211 Current I Q t is equal to the rate at which charge flows through a Electric Current and Direct Current Circuits. pdf 0 downloads chapter 21 electric current and direct-current circuits

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
