  3. 6. a form of energy caused by the movement of electrons.
  4. 7. resistor, a battery, and a closed conducting loop What are the requirements for a circuit?
  5. 8. a device that opens or closes a circuit
  6. 9. the rate at which charges pass through a given point; how fast charge is moving
  7. 11. circuit a closed electrical circuit in which the current is divided into two or more paths and then returns via a common path to complete the circuit

  1. 1. What is the unit for voltage?
  2. 3. a material that does not allow heat or electrons to move through it easily
  3. 4. circuit a circuit in which all parts are connected end to end to provide a single path of current
  4. 5. Law the current in a circuit equals the voltage difference divided by the resistance
  5. 10. positive end of the battery to the negative end of the battery How does electrical energy flow in a battery?
  6. 12. a material's opposition to the flow of electric current; when the movement is charge is slowed or more difficult
