Across
- 2. a closed loop that electrons can travel in
- 4. converts electrical energy into sound
- 6. a circuit attached as branches
- 8. a material that allows electric charge to move through it as an electric current
- 10. converts electrical energy into heat and light
- 11. lets electrical current travel through it
Down
- 1. when closed, it completes the circuit, allowing the circuit to flow
- 3. a material or method that restricts the transfer of either heat or electricity
- 5. is a circuit in a chain
