Slide2CELLS The cell
is the basic structural and functional unit of all known living
organisms
. It is the smallest unit of life that is classified as a living thing, and is often called the building block of life
.
Organisms can be classified as
unicellular
(consisting of a single cell; including most
bacteria
) or
multicellular
(including
plants
and
animals
). Humans contain about 10
trillion
cells
. Most plant and animal cells are between 1 and 100 µm and therefore are visible only under the microscope
.
Slide3BATTERY
An electrical
battery
is one or more
electrochemical cells
that convert stored chemical
energy
into electrical energy. Since the invention of the first battery (or "
voltaic pile
") in 1800 by
Alessandro Volta
and especially since the technically improved
Daniell cell
in 1836, batteries have become a common power source for many household and industrial applications. According to a 2005 estimate, the worldwide battery industry generates in sales each year with 6% annual growth.
Slide4ADVANTAGE OF CELL Cell can movable.Cell can store electrical energy.Cell provide movabulity to the electrical appliances.Cell are carriable hance can be effectivety use in remote aeria.
Slide5Combination of cellWe can combine tow or cell to form a battery . This combinat can be of two form1-SERIES
COMINATION-
2- PARALLEL COMBINATION-
Slide6SERIES COMBINATION the combination of cell in which the positives terminalof one cell get conneted with the negative terminal to other cell. This combination form a chain.
Slide7Parallel combination In parallel combination the positive terminal of one cell get
Connect with positive terminals of next cell and similar happens with the negetive terminals
Slide8Solar cell
A
solar
cell
is a
solid state
electrical device that converts the energy of
light
directly into
electricity
by the
photovoltaic effect
.
Assemblies of solar cells are used to make
solar modules
which are used to capture energy from
sunlight
. When multiple modules are
assembled
t,
the resulting integrated group of modules all oriented in one plane is referred to in the solar industry as a
solar panel
. The electrical energy generated from solar modules, referred to as
solar power
, is an example of
solar energy
.
