- 7. consists of coil of resistance wire and contact point
- 8. changes light energy into electric energy
- 10. uses symbols rather than pictures for components
- 12. several cells connected together
Down
- 2. aka potentiometer; a variable resistor
- 3. current having a flow of positive charge
- 5. measures potential difference
- 9. devices designed to have specific resistance
- 11. closed loop where particles flow around
