Electrical Energy

6. having conductivity; allowing heat or electricity to travel through it
8. the long-term change in the Earth's average temperatures and weather conditions
10. also known as electric potential difference it represents the force that pushes electric charges through a conductor
11. a certification system that helps consumers identify energy-efficient products
13. the rate of flow of electric charge/electrons in a circuit
14. relating to the whole world; worldwide
15. electrical circuits where components are connected across common points, providing multiple paths for current to flow
17. the amount of energy that is transferred per second
18. a representation of an idea, an object, a process or a system
21. available as another possibility or choice
22. a simple electrical circuit that only has one path for current to flow through

1. hydrocarbons formed from deeply-buried, dead organic material subject to high temperature and pressure for hundreds of millions of years
2. scientific law that describes the relationship between current, voltage, and resistance (V=IxR)
3. parts or elements of a larger whole
4. a graphical representation of an electrical circuit
5. a closed path that allows electricity to flow
7. the process through which heat is trapped near Earth's surface by substances known as 'greenhouse gases’
9. relating to electricity
12. the opposition that a substance offers to the flow of electric current
16. devices that use electricity to perform a function
19. any component of a circuit that consumes power or energy (e.g. light bulb)
20. an electrical component that can disconnect or connect the conducting path in an electrical circuit
