    Parallel Series
AI Thread Summary
The discussion focuses on calculating voltages and charges in a circuit involving capacitors. The user seeks clarification on the configuration of capacitors, initially believing c1 and c5 are in parallel, while c3 and c4 are in series. It is clarified that c1 and c5 are not in parallel due to other connections, while c3 and c4 are confirmed to be in series. The user is advised to systematically replace connections with their equivalents to simplify the circuit analysis. The conversation concludes with encouragement as the user prepares to apply the corrections.

Ok this should be an easy one. I am trying to calculate voltages and charges on each capaciter. But first I want to make sure I understand the picture correctly, because soemthing isn't matching

c1 and c5 are parallell to each other. c3 and c4 are parallel to each other. then c15, c2, and c34 are in series with each other?
please correct me if I'm wrong. thanks

What you need to do is systematically replace unambiguous examples of parallel or series connections with their equivalent, then reexamine the circuit and do it again, repeating the process until done.

For example, c1 and c5 are not really in parallel, since the other capacitors are connected between them. But C3 and c4 are definitely in series, since they are directly connected. Start there.
 
o wait a minute. so C3 and c4 are in series. then c34 is parallel to c2. then c1 is in series with c234 which is in series with c 5
ok I am gunna try this out and see if i get the right answer, thanks
 
Now you're cooking. :wink:
 
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
