PHYSICS

1. an arrangement of electrical components such that a current flows along two or more paths
3. a measure of the rate at which work is done
5. a type of resistor whose resistance is strongly dependent on temperature
8. an electrical component that is used for controlling temperature and voltage
10. a measure of the difference in electrical energy between two parts of a circuit
11. emits light
12. an object or type of material that allows the flow of charge
14. any various substances that block the flow of electrical or thermal currents
15. a quantity whose value can change
17. an electrical component that is used for controlling temperature and voltage

2. negatively charged subatomic particles in the nucleus of an atom
4. a type of circuit in which resistors are arranged in a chain so the current has one path to take
6. a measure of the opposition to current flow in an electrical circuit
7. an electrical component that allows the flow of current in only one direction
9. the rate of flow of electric charge
12. a characteristic of a unit of matter that expresses the extent to which it has fewer electrons than protons a stable subatomic particle that has a positive charge
13. a single electrical source that uses chemical reactions to produce a current
16. the ability to exert a force causing displacement of an object
