AMT 111 BASIC ELECTRICITY Flashcards
When electrons are impacted by an
o u t s i d e f o r c e , t h e _______
electrons will be ejected from the
atom and it will flow in space to
find a atom to attach to.
Valence Electrons
is a substance that cannot be reduced to a
simpler form by chemical means.
Element
is usually caused
when non-conductive materials,
such as rubber, plastic, or glass,
are rubbed together causing a
transfer of electrons, which results
in an imbalance of charges
between the two materials.
Static Electricity
is the defined as the flow of electric charge.
Electricity
can be broken down into a simpler type of matter
(elements) by chemical means (but not by physical means)
Compound
In a stable and balanced state, _____are equal to the number of protons
Electrons
Anything that occupies space
Matter
It consists of three particles
Atom
6 sources of electricity:
Friction, Chemical Action, Heat Action, Light Action, Pressure, Mechanical Action.
has properties that are different from its component
elements
Compound
is a buildup of an
electrical charge on the surface of
an object.
Static Electricity
Has mass
Matter
consists of only one kind of atom
Element
When it attaches to a new one, an
electron from that atom will be
ejected and it will find a new atom
t o attach to. Th e c y c l e will
continue on and on, and this what
we call electric Electric current.
Valence Electrons
It has 4 states
Matter
It is a static electricity which is generated by
rubbing two materials.
Friction
consists of atoms of two or more different elements bound together
compound
It holds the protons in place (in the center)
Neutrons
4 states of matter
Solid, Liquid, Gas, Plasma
are electrons on the outermost
layer of an atom.
Valence Electrons
are the substance that does not allow heat or electricity to pass through them.
Insulators
Three particles of atom:
Protons, Neutrons, Electrons
cannot be broken down into a simpler type of matter by
either physical or chemical means
Element
Photo cells are semi- conduction devices which convert light electrical energy directly into
electrical energy. Either sunlight or
artificial illumination may be employed.
Light Action
It is the building block of life and matter
Atom
It is a great deal of the world’s
electricity produced by batteries. These devices generate a different potential means of chemical action.
Chemical action
often described as being either static or dynamic. The difference between the twois
based simply on whether the electrons are at rest
(static) or in motion (dynamic).
Electricity
- It is a difference of potential appears across the face of certain crystal such as quarts, when they are squeezed or stretched. This is called piezo-electricity.
Pressure
is a chemical combination of two or more
elements. Water is one of the most common compounds
and is made up of two hydrogen atoms and one oxygen
atom.
Compound
All electricity in large useful amount is
at present produced by rotating machines working with the use of magnets. These machines, known as generator, are turned by water power, gas engines or steam engines and sometimes by electric motor.
Mechanical Action
The number of _______ determine what element that object is made of.
Protons
Two dissolution metals bonded together in a
junction when heated, exhibits a different potential. This
bond is called thermocouple. Electricity generated by heat
action is called thermoelectric.
Heat Action
is a property of a material.
Conductivity
Materials that have the characters to behave like conductors, as well as insulators under different
conditions, are known as ________.
semi-conductors
is produced when an electrical
current flows through a simple conductor such as alength of wire or cable, and as current passes alongthe whole of the conductor then a magnetic fieldis
created along the whole of the conductor.
Electromagnetism
Elements with high conductivity, which have very mobile electrons, are called?
Conductors
There is only one
__________
in the outermost
shell. (Conductors)
valence electron
The small magnetic field created around the conductor has a definite direction with both the “_____” and “_____” poles produced being determined by the direction of the electrical
current flowing through the conductor.
North and South (electromagnetism)
How many zeros in kilo (k)
3
micro zeros (u)
6 zeros (10^-6)
serve a very important purpose: they prevent the
flow of electrons. Popular insulators include glass, rubber,
plastic, and air.
Insulators
These are the types of materials we want to use to make wires
and other components which aid in electron flow. Metals like copper, silver, and gold are usually our
top choices for good _______.
Conductors
Some elemental types of atoms are better than others at releasing their electrons. To get the best
possible electron flow we want to use atoms which don’t hold very tightly to their valence electrons. An element’s conductivity measures how tightly bound an electron is to an atom.
Conductivity
How many zeros in hecto (h)
1 (10^2)
nano zeros (n)
9 zeros (10^-9)
are the
substance that
transmits heat or
electricity through
them.
Conductors
Elements with low conductivity are called?
Insulators
There are four
valence electrons
in the outermost
shell.
Semi conductor
How many zeros in Mega (M)
6
There are eight valence electrons in the outermost shell.
Insulators
how many zeros in deci (d)

materials that may
act as a conductor,
as well as insulators
under different
conditions, are
known as
