Question about basic Circuit, parallel and series connect

AI Thread Summary
R2 and R4 are neither in series nor in parallel according to the definitions provided. Series connections require components to be connected end to end, while parallel connections involve components connected to the same two nodes. The discussion clarifies that the configuration in question does not meet either criterion. Understanding these definitions is crucial for accurately analyzing circuit behavior. The conclusion emphasizes the importance of correctly identifying resistor arrangements in circuit analysis.

Homework Statement


if I have something looks like the photo attach, could I say that
R2 and R4 are in series?

It asks to compute the current through the R2 branch, but I am curious about these two resistors are in series or not.



Homework Equations


definition of series and parallel connect.
Series: connecting end to end
Parallel: connecting to two same node


The Attempt at a Solution



No, they are not at all in parallel

Thread 'Errors and significant figures'

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'

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...
