Electricity Terms

2. a unit that measures electric current
3. the difference in charge between two points on a circuit
8. a force is said to do this if, when acting, there is a displacement of the point of application in the direction of the force
10. the complete path of an electric current
11. a measure of the difficulty of passing an electric current through a conductor
13. the production of an electromotive force (i.e., voltage) across an electrical conductor due to its dynamic interaction with a magnetic field
15. a type of material that allows the flow of electric current in one or more directions
17. a circuit that has two or more paths for current to flow through
18. the presence and flow of electric charge
19. the rate of flow of electric charge, measured in amperes

1. a property of objects which can be transferred to other objects or converted into different forms
4. states that the current through a conductor between two points is directly proportional to the voltage across the two points
5. the rate of doing work, or the amount of energy consumed per unit time
6. the ratio of useful work performed by a machine or in a process to the total energy expended or heat taken in
7. a measure of electric potential, or the energy that could be released if electric current is allowed to flow
9. a circuit in which resistors are arranged in a chain, so the current has only one path to take
12. a form of kinetic energy that is caused by moving electric charges
14. an electrical resistance between two points of a conductor when a constant potential difference applied between these points produces in this conductor a current of one ampere
16. an electrical component or portion of a circuit that consumes electric power (ex. appliances and lights)
