  1. Apr 21, 2006 #1
    When electric charges occur in a system, it is possible to determine the electric energy of the system. Which of the following is false:

    d. The electric energy of the system can only vary when it is converted into thermal energy

    Why is this answer False?
    What other factors affect electric energy?

    Thank You

    You connect a battery to an electrical motor. some of the energy goes into thermal energy but some goes into work that makes the motor rotates. That is just one possible example
