Cheers to anyone who can help me find the voltage in the middle of this circuit

Question 6.png

Starters, tips, anything. Literally don't know where to start with this. Have tried going through a whole set of videos... https://www.youtube.com/playlist?list=PLX2gX-ftPVXW6bFHC_a2wsp7kJgWyeaT0 | Not progressing with this problem, now.

Haven't been taught techniques such as mesh analysis and the like; so, this probably can't be too hard. Problem is I can't find a similar example to use.

hi W,
Tip. Work out the ratio of the two vertical resistive elements in the circuit.
What do you make that ratio.?

When you "measure" voltage (Vo) typically that assumes that that
as shown there is no current being drawn by the "measurer". So
there is no voltage drop across the 2K or 4K.

Rest of the problem is simple current divider and once each leg current
is known then compute voltage drop across either bottom Rs or top Rs
to get at Vo.

Regards, Dana.

You don't need mesh analysis or anything of the sort.

You are trying to tackle the entire problem at once. Instead, break it down into little problems.

Do you know how to do current division?

Can you solve the following problem to find Ia and Ib?
