Circuit with 2 components. Series or Parallel?

AI Thread Summary
In a circuit with a battery and a capacitor, the classification as series or parallel can depend on the perspective taken. When considering current flow, it may seem like a series circuit due to a single path for current, but both components share the same potential difference, which aligns with parallel characteristics. In the case of a charged and uncharged capacitor, they are considered in parallel despite having one current path, as they maintain the same voltage. The presence of an oscilloscope does not change the fundamental classification but may influence the analysis approach. Ultimately, both interpretations can be valid depending on the context of the measurement or analysis.

Homework Statement


Say I have a circuit with only 2 components, a battery and a capacitor. Is this circuit considered series or parallel? What about a charged capacitor and an uncharged one? Does the fact I have an oscilloscope connected to the capacitor to read the voltage across it affect this answer?

The Attempt at a Solution


I can see arguments for either answer being valid. For the first scenario, it makes sense to say series because there is only one route for current to flow, but the potential difference across both the battery and the capacitor are the same, which is part of the definition of a parallel circuit. In the second situation I know the answer is that the two capacitors are in parallel even though there is only one path for current to follow, justifying the use of the same potential difference for the logic. Which would then make the first situation a parallel circuit. I'm just not sure if I've thought it out correctly.

Yes, for just two components whether they are taken to be in parallel or series depends upon how you view the circuit or what you're measuring. Depending upon the analysis you want to do, one point of view or the other may make life easier, but both ways are valid.

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...
