Why do the capacitors in this circuit have the same voltage?

AI Thread Summary
Capacitors in the discussed circuit maintain the same voltage because they are connected to the same two points, regardless of their arrangement. While they can be viewed as being in both series and parallel, the critical factor is that voltage is always relative between two points. The understanding that capacitors in parallel share the same voltage is reinforced, even when the circuit configuration changes. The distinction between series and parallel becomes less significant in this context. Ultimately, the key takeaway is that the voltage across both capacitors remains equal due to their connection to the same points.

Homework Equations


C = Q/V

The Attempt at a Solution


I understand that capacitors in parallel have the same voltage, but wouldn't they be in series after the switch is flipped, since no current goes to the left most portion of the circuit.

Okay I guess that makes sense.
 
Doesn't actually matter if you call it series or parallel.Voltage is always relative (eg it's always measured between two points). Both capacitors are connected to the same two points so must have same voltage.

Ah, I get it, that makes more sense. Thank you.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

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...

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}...
