Across
- 2. around the outside of the atom is a cloud of electrons.Electrons have a negative electric charge
- 7. a pathway made of wires that electrons can flow through
- 8. a measurement of how well a material or object is able to conduct electricity
- 10. usable power of the resources eg oil used to produce usable power
- 12. the build up of an electrical charge on the surface of an object static charges do not flow as current
- 13. A form of energy that is caused by the movements of some of the tiny particles that make up atoms
- 15. an energy transformation is the change of energy from one form to another there are many different forms of energy such as electrical thermal, nuclear, mechanical, electromagnetic, sound and chemical
Down
- 1. circuit an incomplete electrical circuit in which no current flows.
- 3. charges produced or caused by static electricity
- 4. incredibly tiny units of matter each is made up of protons and electrons
- 5. a sealed container that holds chemicals which are used for producing electricity also called battery
- 6. a fine wire usually found in an incandescent light bulb that is made to glow by the passage of an electric current
- 7. the flow of an electric charge in an electronic circuit the current is the flow of electrons
- 9. a device that is used to control the flow of electricity the flow of electric circuit
- 11. a machine that produces electricity
- 14. found at the center or nucleus of an atom protons have a positive electric charge
