13. a variable that doesn't depend of that on another
16. a picture that represents the components of a process
17. electrical circuit that is not complete
19. the SI unit of electromotive force, the difference of potential that would drive one ampere of current against one ohm resistance
20. a device designed to introduce resistance into an electric circuit
21. a device that stores chemical energy and converts it to an electrical energy
22. a substance or material that allows electricity to flow through
24. a calibrated instrument used for measuring the potential difference between two points
25. all variables other than the independent variable are controlled or held constant so they don't influence the dependent variable

2. is the capacity for doing work
3. a circuit that is fully complete
7. a piece of steel or iron that attracts certain substances such as iron
8. all components are connected end-to-end to form a single path for the current to flow
10. a flow of electrical charge carriers
11. a variable that depends of that on another
12. time or rate of doing work or delivering energy
14. the science of dealing with electrical charges and currents
15. the energy generated by the movement of electrons from one point to another
18. a device for measuring electromotive force or potential difference by comparison with a known voltage
23. the law that for any circuit the electrical current is directly proportional to the voltage and is inversely proportional to the resistance
