Electronic Components

4. allow current to flow in only one direction.
6. a diode made of silicon.
8. indicates how close the actual resistance is to the rated value.
12. heart of all electronic circuits.
14. a resistor which its value can be adjusted.
15. a diode built for converting alternating current to direc current.
16. a diode used to separate information from transmitted radio signals or carrier waves.
17. diode made of germanium.
18. approximate electrical resistance expressed in ohms.
19. used to convert energy from one form to another.
21. means a lack of electron.

1. regulating-type resistors.
2. thin central layer which controls the electrons.
3. establish correct current and voltage levels throughout the circuit.
5. diode conducts a large and continuous current.
7. impurity atoms.
9. diode becomes poor conductor and there is no continuous flow of charge to the junction.
10. tells the maximum rate at which a resistor can safely dissipate electrical energy as heat.
11. process of adding impurities to a pure semiconductor
13. materials whose ability to conduct electricity falls somewhere between that of an insulator and that of a conductor.
20. he came up with a better amplifying device than the point contact transistor.
