Installer technician conventional Questions
and Answers 2024/2025
Why do only the outer electrons leave their orbit shells?
Only outer electrons leave their orbit shells, because electrons furthest from the
nuclear us are more easily freed from their orbits due to a weaker electrostatic force
What is required to have a balanced atom?
The number of electrons must equal the number of protons to have a balanced atom
List the capacity for each of the first for orbital shells of an atom
Shell 1=2 electrons, shell 2= 8 electrons, shell 3= 18 electrons, and shell 4 is 32
electrons
What is the maximum electron capacity of a valance shell?
The valence shell can hold a maximum of eight electrons
Electrons in orbit nearest the nuclear us contain———-energy than those in more distant
orbits.
Electrons in orbit nearest the Nicolas contain less energy than those in more distant
orbits
What happens to a valance electron that has enough energy added to it?
A valence electron that has enough energy added to it, moves away from its Atom
What is the major factor that determines the category of a particular element?
The number of electrons in the valance shell of determines the element category
How many valence electrons are there in a good conductor?
Good conductor has only one or two valence electrons
List, gold, silver, and copper in the order of the best connectivity
Silver, copper, gold
Why do metals that each have only one valence electron differ in their conductivity
Metals that each have one valance electron differ in their conductivity, because of the
way their atoms pack together into a solid structure
Describe the two characteristics of an insulator
The two characteristics of an insulator are its valence Shell is almost filled and tends to
be fairly stable and two it, tries to finish, filling its valance shell by capturing
additional free electrons.
How many valence electrons are in a semiconductor
A semiconductor has four valence electrons.
Name of the two types of electron current flow
Random drift and directed. Flow are the two types of electron current flow.
What causes electrons to be knocked loose and travel randomly from one atom to another
The movement of atoms in materials that are conductors and the agitation as they
collide cause electrons to be knocked loose and travel randomly from one atom to
another
What can force electrons to all move in the same direction?
1 V is the amount of force required to produce a current of one amp through a
resistance of one ohm
What are three alternate ways to Express five and 3MA
5 microvolts, 5/1000000 volts or 0.00005 V, and three Milla amps. 3/1000 amps or
0.003 A
What are two alternate ways to express 2 megavolt?
2MV or 2 million volts
What are two alternate ways to express for kilovolts?
4kv or 4000 volts
Which orbital shell has a maximum electron capacity of 18 electrons
The third shell
Why are semiconductor material is not good conductors nor good insulators
The valance shells are only half filled
Which of the following best describes a conductor
Elements that have a small number of electrons in the Valence shell
Which of the following best describes the relationship between an amp and a coulomb
The number of amps is equivalent to the number of coulombs passing a given point
during one second
