Resistance in kilo ohm and answer in volt.

In a voltage divider circuit there are always 2 resistors in series say r1 nd r2.
The output is taken across say r2.
Then the output voltage will be;
Vo=(r2/r2+r1)vi.
Vi is input voltage.
Therefore;
Vo=(68/68+68)24=24/2=12.
The output is taken across say r2.
Then the output voltage will be;
Vo=(r2/r2+r1)vi.
Vi is input voltage.
Therefore;
Vo=(68/68+68)24=24/2=12.

Unkown output voltage means voltage drop across the last element. Here bothresistance value is same so 12v is coming.

@All.
Hi, Here it is mentioned as a voltage divider. That means, its a simple series circuit across one voltage source.
Unless otherwise mentioning the output terminals, we cannot assume that the unknown voltage is across one of the resistance or so.
I think input data in the question has to be elaborated. Correct me, if I am wrong.

I think here applying voltage division rules this used only for resistors connected with voltage source if not then the converted number of resisters is only 2 resistor formate so,
If you find.
R0 =Vi* (R1/R1+R2).
R0=24* (68/68+68) =12.
If you find.
R0 =Vi* (R1/R1+R2).
R0=24* (68/68+68) =12.
