Equivalent capacitance; complex circuit

AI Thread Summary
The discussion focuses on finding the equivalent capacitance of a complex circuit involving multiple capacitors. The user initially attempts to simplify the circuit by calculating the equivalent capacitance of capacitors C2, C3, and C4, but struggles with the subsequent connections. Suggestions are made to group the capacitors into manageable sections, leading to a clearer path for calculating the overall equivalent capacitance. The proposed grouping effectively simplifies the circuit analysis. Ultimately, the user successfully resolves the problem with the provided guidance.

[SOLVED] Equivalent capacitance; complex circuit

Homework Statement



Hello, I was assigned a problem where we are supposed to find the equivalent capacitance of a circuit, and then use that to answer some other questions. However, I'm not sure how to handle this circuit.

Homework Equations



We're using the equations where C(series) = (C1^-1 + C2^-1 +...)^-1 and C(||) = C1 + C2 + ...


The Attempt at a Solution



My immediate thought was to find the equivalent capacitance of C2, C3 and C4 using C234 = C2 + (C3^-1 + C4^-1)^-1. But, after that I'm not quite sure what to do, since the capacitors are now connected in a pattern where C1 and C234 connect together on a path that connects between C5 and C6. I didn't post the numbers for each capacitor as I figure I don't need to burden you with number crunching, but any ideas on how to simplify this circuit would be immensely helpful. Thanks.

My suggestion is to group as follows:

1. CA = C3+C4
2. CB = C5 + (CA) + C2
3. CC = C6+C1
4. CD = CC+CB

With the + symbol indicating the equivalent capacitance which is not necessarily an addition.
 
Thank you very much, that did the trick.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
Thread 'Correct statement about a reservoir with an outlet pipe'
The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
Thread 'A bead-mass oscillatory system problem'
I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
