    Electrical Energy and Power In a circuit, as a charge moves through the  battery, the electrical potential energy of the  system is increased by ΔQΔV The chemical potential energy of the battery  decreases by the same amount As the charge moves through a resistor, it  loses this potential energy during collisions  with atoms in the resistor The temperature of the resistor will increase

    Energy Transfer in the Circuit Consider the circuit  shown Imagine a quantity  of positive charge,  Q, moving around  the circuit from point  A back to point A

    Energy Transfer in the Circuit,  cont Point A is the reference point It is grounded and its potential is taken to  be zero As the charge moves through the  battery from A to B, the potential energy  of the system increases by  Q V The chemical energy of the battery  decreases by the same amount
