AC T1 Flashcards
it is a property of matter that results from the presence or movement of electric charge. According to modern theory, matter is electrical in nature.
Electricity
it is anything that occupies space and has mass
matter
It is the smallest particle of an element that is capable of independent existence
atom
it is the smallest particle of matter that is capable of free existence
molecule
it is a substance that cannot be decomposed any further by chemical action
element
it is a combination of two or more elemens
compound
is a material composed of two or more substances, each of which retains its own characteristic properties
mixture
positively charged particle
proton
negatively charged particle
electron
particle with neutral charge
neutron
represents the number of protons or electrons of an atom
atomic number
it represents the sum of protons and electrons of an atom
atomic mass
atom that has net positive or negative charge resulting from unequal number
ion
it is an energy keek or region
shell
electrons found in the outermost shell
valence electrons
these are materials that allow the essentially free passage of current when connected to a battery or other source of electrical energy
electrical conductors
also called dielectrics
electrical insulators
these are materials that posses low conductivity or offer a relatively high resistance to the flow of electric current
electrical insulators
these are materials that have conductivity about midway between good conductors and good insulators
electric semiconductor
it is the motion or transfer of charges from one region of a conductor to another. Its unit is the Ampere (A) named after André Marie
Ampère.
electric current
electricity from heat
thermoelectricity
electricity from friction
static
electricity from pressure
piezoelectricity
electricity from a chemical action
electrochemistry
electricity from light
photoelectricity
electricity from magnetism
magnetoelectricity
the unit of voltage
Volt (V)
it is the driving force behind current flow
electric voltage
it is the motion or transfer of charges from one region of a conductor to another
electric current
it is the difference in the electric potentials of two charged bodies. Its unit is the volt.
electric potential difference
it is the property of a material that limits the amount of flow of current and converts electric energy to heat energy. Its unit is the Ohm
electric resistance
it is defined as the rate
at which electrical energy is expended or used up. It is the rate electric energy is converted into another form, such as light, heat or mechanical energy (or converted from another form into electrical energy). Its unit is the Watt (W).
electrical power
it is the capacity to d o work. It is measured in Joules
energy
it is a collection of electrical elements interconnected in some specific way through which electric current flows or it is intended to flow.
electric circuit
is the cost of electrical energy consumed.
energy charge
is the user’s highest rate at which energy is consumed in kilowatts.
maximum demand
is the billing fee related to the maximum charge.
demand charge
refers to the device or component that consumes electrical power in a circuit.
load
These include incandescent bulbs, fluorescent lamps, LED lights, and other types of lighting used for indoor and outdoor illumination.
lighting fixtures
Devices such as electric heaters, electric furnaces, and baseboard heaters that use electricity to generate heat
heating appliances
Air conditioners, refrigerators, and freezers are examples of electrical loads used for cooling purposes.
cooling appliances
are used in various applications, including fans, pumps, compressors, conveyor belts, and various industrial machinery.
motors
Devices like televisions, computers, washing machines, dryers, dishwashers, microwaves, and other household appliances are common electrical loads in residential settings.
electronic and appliances
include various
machinery, motors, and equipment used in manufacturing processes,
such as presses, lathes, CNC machines, and welding equipment.
industry equipment
Electric saws, drills, grinders, and other power tools used
in construction and workshops are considered electrical loads.
power tools
including electric furnaces, heat pumps, and air conditioning units, are significant electrical loads in both residential and commercial
buildings.
HVAC systems
