this video is about importance of
0:04
uses now electricity is a phenomenon of
0:07
great importance in our day-to-day life
0:10
it is a form of energy that is
0:12
controllable and is convenient to use
0:14
you can find its uses almost everywhere
0:17
be it at your school home hospital or
0:19
any other places now this whole chapter
0:22
called electricity is all about giving
0:24
you an basic idea about electricity and
0:27
electrical phenomena that is what is
0:30
electricity and how does it flow in
0:32
electric circuit apart from these
0:34
questions you might also ask about the
0:37
factors of methods that can be used to
0:39
control or regulate electric current
0:41
flowing through an electric circuit now
0:44
this lesson which I would cover in few
0:46
videos is all about answering these
0:50
questions so modern devices which we use
0:53
in our day-to-day life for example
0:55
computer camera fan electric bulb
0:58
battery cell phone television
1:00
refrigerator Etc all require electricity
1:05
operation so electricity is the most
1:07
clean and convenient form of energy in
1:09
our day-to-day life so here we will
1:12
learn about basics of electricity in
1:17
lesson before moving any further I would
1:19
like to emphasize that electricity and
1:22
electrical phenomenon give us a wide
1:24
variety of well-known effects such as
1:26
Lightning static electricity
1:28
electromagnetic indu ction and electric
1:33
more now here lightning is the
1:36
occurrence of natural Electric discharge
1:38
of very short duration and high voltage
1:41
between a cloud and the ground or within
1:44
a cloud mostly a made by a bright flash
1:47
and thunder now static electricity is an
1:52
imbalance of electric charge within or
1:54
on the surface of a material it often
1:57
happens when you rub things together for
2:00
example if you rub balloon against a
2:02
jumper a few times it sticks to you
2:05
lightning which I defined earlier is
2:07
also caused by static electricity
2:10
electromagnetic induction is the
2:12
production of an electric current by
2:14
changing the magnetic field enclosed by
2:17
an electric circuit the most common use
2:20
of electromagnetic induction is in the
2:24
generator the electric current is
2:26
nothing but the flow of electric charge
2:29
so here here we now know about how
2:31
important electricity is for our
2:33
day-to-day life to understand its
2:36
importance yourself just recall or
2:38
notice the time when you have power cut
2:42
household or something goes bad at your
2:45
house or school and you have a lights
2:48
out situation even for a few minutes I
2:51
know situation is tough as your
2:53
appliances like television fan
2:55
refrigerator AC Etc stop
2:58
working after finishing this video just
3:01
think if we did not have electricity
3:04
what would we do in the evening after
3:06
sun went down I know you could probably
3:09
come up with a list but what I want here
3:12
is for you people to recognize the
3:14
importance of electricity and its
3:17
uses for more notes and study material
