You are presented with the question "Powering a device with a battery requires a path for electrons to flow through  " and the following answer choices: 
- electromagnetic energy
 - direct energy
 - rays or beams
 - hydrogen and oxygen
 - heat energy
 - a closed circuit
 - kinetic energy
 - an object

Now knowing that powering an electrical device with a battery requires a path for electricity to flow through a closed circuit and an electrical current is a flow of electrons, choose the best answer.


 

      a closed circuit
