hi seb,
To check why not assign values to R2,R3 & R4||R5
Let V=9v R2 =3 , R3=3 and R4 & R5 =6 ohms each.
What Vout do you get.?

hi,
Let R2 = 3 ohms , R3 = 3 ohms,.
If R4 = 6 and R5 =6, in parallel thats 3 ohms.
So you have a circuit with 3 resistors of 3 ohms in series., with a 9V supply.
What voltage must be across each 3 ohms.??

R1 doesn't play any role in the V5 voltage calculation
R4 & R5 combined are a 3 ohm resistor, so as a voltage divider the V5 is 1/3 of the 9V meaning 3V

hi seb,
Yes.;)

So to check your equation. replace R2,3,4,5 with values we have used and you should get the same 3V answer if your equation is correct.
OK

hi D,
It is not a problem. OK.:)
We try to make the TS work it out themselves, sometimes it has to be step by step process.
