Hello friends, in this video we are going
to see series connections of the resistor.
Let us
consider a circuit, such a way that resistors
are connected one after the other having no
connection between them.
For example, here it is shown that the three
resistors connected one
after the other between points A and B, such
a way that there won&#39;t be any connection
between
R1 and R2, R2 and R3.Then this particular
connection is called as series connection
of the
resisters and the equivalent resistor for
this will be nothing but, simply addition
of R1,R2 and R3.
suppose I am having n number of resistors
connected in series, then obviously the equivalent
resistance for the series combination, nothing
but addition of all the resistors connected
between points A and 
Suppose I am having all the resistors of the
same value which is nothing
but R. If R1 is same as R2 is same as R3 is
same as Rn, which is nothing but R, then I
can say
equivalent resistance will be n*R. where I
can say n is 
number of resistors connected in series.
As far as structure is concerned I can say
series combination of resistors means resistors
are
connected one after the other such a way that
there won&#39;t be any connection between
two
subsequent resistors but as far as the electrical
parameters are concerned, I can say 
same
current is flowing through all of them.
So I can say, if same current is flowing then
resistances
are in series.
so here we have seen as far as structure is
concerned, if resistors are connected
one after the other, then I can say the resistors
are in series, at the same time if this resistances
are connected to the battery battery will
give up the current, which will remain same
for all of
them.
Then the concept is same current is flowing,
all the resistances connected between the
points are in series.
Here we have seen how the series connection
of resistances will look
like.Thank you.
