Another Question, What will be readings for the 2 voltmeters?

Regards,

Hint:
The total voltage around the loop is 24 Volts
The total resistance around the loop is 18 K Ohms
Therefore the current in the loop is 1.333... mA

Apply Ohms law to each resistor and compute the voltage drop. The three voltage drops should add up to 24. So starting with +12 Volts subtract the voltage drops until you get to -12 volts.

Are you with me?

It does add up to 24 volts, so my next step is subtract the voltage drops starting with +12 volts!

+12 - 2.67 = 9.33
+9.33 - 8 = 1.33
+1.33 -13.33 = -12

So what do i do next?

There is no next. The readings on the two voltmeters are:

Ta Da!

9.33 VDC
1.33 VDC

What more do you want?

I got 8.733 for the top voltage meter and .9334 for the second meter, can you see what I did wrong?

Your IR drop on R1 is off. 2k * 1.33 mA is 2.66 V not 3.66 V
