Basic Electronics

1. An electrical component that can open or close, turning the circuit on or off
3. A conductive metal with a low melting point, ideal for building circuits
5. Also known as electric potential
8. A very conductive metal that is also used in jewelry
11. A measure of how hard it is for electric charge to pass through a point in a circuit
15. Abbreviation. Acts like a diode, but also emits light.
16. An electrical component that impedes the flow of electricity
17. An electrical component that stores and releases electric charge
18. A material that does allow electric current to pass through it easily

2. A measure of how much charge flows through a point in a circuit
4. A common conductive metal formerly known as Cuprum
6. A person who installs electric circuits and electric components in houses and buildings
7. An electrical component that only allows electricity to flow in one direction
9. Always wear one of these when soldering
10. A tiny particle that moves through conductors
12. A material that does not allow electric current to pass through it easily
13. An electronic device that uses all sorts of buttons, switches, chips, and other components to do calculations and processes
14. A portable source of electric energy
