ELECTRICITY:
Electric power is defined
as the rate at which electrical energy is transferred by an
electric circuit. The SI unit of power is the watt.
Electrical power is distributed via cables and electricity
pylons like these in Brisbane, Australia.When electric current
flows in a circuit, it can transfer energy to do mechanical
or thermodynamic work. Devices convert electrical energy into
many useful forms, such as heat (electric heaters), light
(light bulbs), motion (electric motors), sound (loudspeaker)
or chemical changes. Electricity can be produced mechanically
by generation, or chemically, or by direct conversion from
light in photovoltaic cells, also it can be stored chemically
in batteries

Health:
Health
is generally defined as being "a state of complete physical,
mental, and social well-being and not merely the absence of
disease or infirmity". This definition is used by the
World Health Organization (WHO) since 1948.
In 1986, the WHO, in
the Ottawa Charter for Health Promotion, said health is "a
resource for everyday life, not the objective of living. Health
is a positive concept emphasizing social and personal resources,
as well as physical capacities". Classification systems
such as the WHO Family of International Classifications (WHO-FIC),
which is composed of the International Classification of Functioning,
Disability, and Health (ICF) and the International Classification
of Diseases (ICD) also define health. |
