Debugging Logic Flow: Tips and Tricks

AI Thread Summary
The discussion centers on a misunderstanding of a circuit's logic flow involving two power sources and resistors. The user believes that the circuit is straightforward, calculating voltage across a resistor using a voltage divider formula. However, they express confusion about why it isn't simply a circuit with one battery and two loads. Clarification is sought on the correct interpretation of the circuit and the logic behind the calculations. The user is looking for guidance on nodal analysis to better understand the circuit dynamics.

Never mind there, I screwed up my logic flow

I haven't learned nodal analysis yet, but I don't see any thing wrong with V1 =+6V. It's just a simple circuit to me, with two sources delivering power (addictive) with net 18 V ...
so, this leaves us 18 V of battery with two resistors, and using voltage dividers:
Vacross 3000 = 3000/(3000+6000)*18 = +6

I would really appreciate if you can help me understand why this is not just a simple circuit with one battery and two loads.
 
but what was the correct answer!?
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
