8 Science Unit 3 Lesson 3
Across
- 3. a complete close path through which electric charges can flow
- 5. a metal strip in this breaks if the current gets to high in a circuit
- 7. a metal ________ connected to the ground by a thick conducting wire can help protect from lightning strikes
- 8. this type of circuit offers more than one path for electric charges to follow
- 10. a _______ cell that converts sunlight into electricity
- 12. this type of circuit all parts are connected in one path for the electric charges to follow
- 13. GFCI's are often used into electrical outlets that are near water
Down
- 1. changes chemical energy into direct current electrical energy
- 2. a circuit _______ is commonly used today in electrical panels to prevent overloads
- 3. a material in which electric charges can move easily
- 4. a device that uses electrical energy to operate
- 6. a relatively inexpensive metal used for wires
- 9. a dangerous, huge discharge of electrical charges that build up in clouds
- 10. a device that turns electrical devices on and off
- 11. if a short circuit occurs, the wires can heat up enough to cause this
