AI Thread Summary
The discussion focuses on using the Delta to Y transformation to simplify a complex circuit, particularly when traditional series and parallel methods are ineffective. The presence of a 10 and 8 ohm resistor complicates the transformation, but recognizing that points c and f are the same node may provide a solution. Participants suggest redrawing the schematic for clarity and exploring the resistance between specific nodes to facilitate problem-solving. The conversation emphasizes the importance of visualizing the circuit correctly to apply the current distribution method effectively. Overall, the Delta to Y transformation can be a viable approach if the circuit is properly analyzed.

Not sure what I can do to proceed on here: Should I be using the Delta to Y transformation? Wouldn't be able to simplify using simple series and parallel circuits, and hence am looking for any clues I might need to solve this problem.
PS: ForDelta to Y transformation, it seems that the 10 and 8 ohm resistor seems to be preventing me from doing this way.

Points c and f are connected by a wire, hence are in reality the same node. Does that suggest a way forward?

Maybe you can solve it like this （In China we called it Current distribution method ）

Yes, I think you can. The most difficult problem here is that the schematic is drawn in a confusing way. Redraw it so it makes more sense to you.

@gneill has given you a way forward, pursue that. For example what is the resistance between node e and node cf?
 

Thread 'Rolling without slipping on a curved surface'

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 '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...
