4. negatively charged particle
5. a container in where chemical energy becomes electric
9. loop where electricity can flow through the whole thing
11. a safety device consisting of a strip of wire that melts and breaks an electric circuit if the current exceeds a safe level
12. loop where electricity cannot flow through the entire circuit
14. a material that easily allows electricity to flow through
16. continuous physical force exerted on or against an object by something in contact with it
17. material that allows for little electricity to pass through
19. an electric current that reverses its direction many times a second at regular intervals, typically used in power supplies.
20. the SI unit of power, equivalent to one joule per second, corresponding to the power in an electric circuit in which the potential difference is one volt and the current one ampere.

1. a particle with a neutral charge
2. comprises branches so that the current divides and only part of it flows through any branch
3. all components are connected end-to-end to form a single path for current flow
6. the unit of electromotive force
