hello friends in this video we are going
to see one problem-solving technique
that is work a divider
so yeah we are having one series circuit
and number of resistances connected in
series in one room
the circuit this resistance cells are
excited by a voltage so free
so there will be a campus in colleges
that will be I I will pass through a
resistance r1 Avella a voltage across it
that is we were saying that I is passing
through r2 because the CD circuit it
will develop a voltage we do and so on
up to VN now suppose I want to get the
expression of V 1 V 1 is nothing but I
into R 1 simple Ohm's law and I will be
equal to would they supply divided by
total resistance in the circuit that is
1 1 plus R 2 plus R 3 up to RN so if I
substitute this over here what I will
get is voltage across R 1 equal to R 1
multiplied by total voltage V here it by
summation of all the distances connected
in series so basically why will they
divide a rule I can directly write this
expression let us apply this project for
V 2 V 2 is a voltage across r2 so I can
say V 2 equal to R 2 because I go on the
voltage across r2 hence R 2 divided by
summation of all the resistances in the
series
multiplied by supply voltage
same concern we can apply and care
voltages across all the resistances and
certain things we need to keep in mind
and what are those things
voltage divider rule popularly known as
Vidia is applicable for see this
resistances
for me
one loop the only one who picture form
and number for the sensation in series
and secondly it can be applicable for
any number of series resistances
meaning unlike current source
repeat unlike current divider rule where
it is applicable only for two
resistances in parallel media can be
applicable for any number of resistances
connected in series forming one loop
thank you
