Across
- 3. colour of live wire
- 5. circuit where the current divides into 2 or more paths
- 6. a very big spark
- 11. used to measure potential difference
- 14. collection of power cables and transformers
- 18. do not allow electrical charges to move through them
- 20. component that resists the flow of current
- 22. created by a charge object stretching into space
- 24. bulb which gets hot so resistance increases (S shaped)
- 25. allow electric charges to move through them
- 27. rate of flow of electric charge
Down
