Reducing Equivalent Resistors and Capacitors

AI Thread Summary
The discussion focuses on reducing a circuit with equivalent resistors and capacitors, where all resistors are R and all capacitors are C. The user successfully reduced two capacitors in series and two resistors in parallel, resulting in equivalent values of C_eq = 0.5C and R_eq = 0.5R. There is confusion regarding the configuration of two central capacitors and whether they are in parallel, while the other capacitor's relationship to them is also questioned. Clarification is provided that the central capacitors are indeed in parallel, but the far-left capacitor is not due to the presence of resistors. The user seeks further assistance on simplifying the circuit and calculating impedance.

Homework Statement



Reduce the circuit as much as possible. All resistors have R and all capacitors have same C.

And this is my reduced one (I only reduced two capacitors in series and two parallel resistors)

The reduced capacitors (the ones in the right corner of that little square) =

1/C_eq = 1/C + 1/C = 2/C
C_eq = .5C

1/R_eq = 1/R + 1/R = 2/R
R_eq = .5R


(Ignore the random squiggly at the bottom)

Anyway - that's as far as I got. I'm not sure if the two capacitors in the center are considered parallel? And if so, is that other capacitor on the far left considered in parallel with them too? (even though there are resistors between them?)

Can you attach the images to your post? I really don't feel like joining facebook just to look at your problem. :smile:
 
oh, sorry - they were supposed to show up!
 
Yeah, the two caps in the middle are in parallel, but the other one you are asking about would not be. Think of parallel as whether or not the wires are connected at both ends. Think of series as whether or not two elements share a common connection. (A fancy name for connection is a node.)
 
Is this as far as it can be reduced?

Hmm...is this it? It seems like something simpler could be achieved somehow...*sigh*

Hello,
Can anyone give me a hint how to calculate the impedance of the following circle ?
Thank you

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 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
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...
