Yes the net voltage is on the R3.

I agree with seyran.

In series connected resistors the current flowing through it ll b same but de voltage gets divided. As the question says voltage across the resistors are zero except at r3 which clearly means the entire applied voltage s across r3.

The resistor r3 is connected at first in series. So, the resistance value of the resistor r3 is high to drop that entire 6volt which may be connected to ground. So there is zero voltage appear across next coming series resistor.

In series connection current is always same so value of current across r3 is also zero hence no voltage.

If all resistors are connected in series, the current flow through the all resistors is always same. So value of current across R3 is also zero.

@Aman.
You should think that we are talking about zero voltage but not for zero cureent. It means all the resistors except R3 contains zero resistance. So all voltage drop is across register R3 which is the total voltage drop due to current flowing through it opposed by its resistance.

In series circuit, value of current remain same. So according to question if value of voltage measure zero across all resistor, means the value of current is zero and it same for all resistor. So answer zero.

It means other than R3 all resistance are zero, because of it in series connection current is same,
If I=0 then no meaning of R3.
But according to kirchoff's circuit is false.
So.
If R1, R2, R4, R5=0 then R3=6 if I=1amp.
If I=0 then no meaning of R3.
But according to kirchoff's circuit is false.
So.
If R1, R2, R4, R5=0 then R3=6 if I=1amp.

Since all resisters are connected in series, such that the current flowing through R3 resister is zero (open circuit) , so therefore vr3=6v.
