Robotics Vocabulary

1. protects a system or equipment from overload and short-circuit faults by cutting off the power to them
3. the amount of force exerted per area.
6. reverses
9. substances through which electricity can flow
10. a combination of apparatus for producing a single electrical effect
12. an electromotive force or potential difference expressed in volts
14. an electric current that is uni-directional, so the flow of charge is always in the same direction
16. flow of electric charge that
18. unit of electrical potential, potential difference and electromotive force in the metre–kilogram–second system
19. a carbon, metal, or metal-oxide film
21. a substance which does not readily allow the passage of heat or sound.
23. serves both as the repository of genetic information and as the cell's control center
24. a unit of power

2. a stable subatomic particle with a charge of negative electricity found in all atoms and acting as the primary carrier of electricity in solids
4. all components are connected end-to-end to form a single path for current flow
5. a mechanical or electronic device that automatically regulates a system to maintain a desired state or set point without human interaction
7. the resistance that one surface or object encounters when moving over another
8. the SI base unit of electrical current
11. comprises branches so that the current divides and only part of it flows through any branch
13. a stable subatomic particle occurring in all atomic nuclei with a positive electric charge equal in magnitude to that of an electron, but of opposite sign
15. the rate of flow of electrons in a conductor
17. a particle of matter that uniquely defines a chemical element
20. a measure of 1,000 watts of electrical power
22. a control system for an operation or process in which there is no self-correcting action as there is in a closed loop
