G -Basic Electronics Flashcards
Which of the following systems have movable electrical contacts that carry the system’s current flow: Electrical systems, electronic systems, mechanical systems, or all of the above?
Electrical systems.
Which of the following devices have no movie parts: Solid state electronic devices, mechanical electric devices, Mechanical systems, or all of the above
Solid state electronic devices.
True or False: Electrical systems can make very fast multiple decisions, remember past events and self-diagnose problems.
False; Electronic systems can do these things.
In the technology of the semiconductor the word semi means:
Semi means that something is half way between two limits.
In the technology of the semiconductor the word conductor means:
Conductor means that the material allows electric current to flow freely through the substance.
The base material for the manufacture of semiconductors is most often:
Silicon.
An N type semiconductor is produced when a covalently bonded silicon crystal is doped with:
Antimony.
A P type semiconductor is produced when a covertly bonded silicon crystal is doped with:
Boron.
As the temperature of a wound resistance wire resistor rises, its resistance value:
Increases.
Resistors are specially constructed devices that can be used to:
Produce heat, produce light, and limit current flows in electrical circuits.
Fixed value resistors can have:
Only one resistance value.
When a resistor’s resistance value is checked with an ohmmeter, it must be:
Isolated from any electrical voltage source.
True or False: A diode results when a P type semiconductor is bonded to an N type semiconductor material.
True.
True or False: A diode testing function can be used to test diodes when using a DMM.
True.
True or False: When a diode is being tested in a reverse bias connection and an audible signal is heard, the diode is serviceable.
False; It means the diode is defective and cannot be used.
