Electric circuits problem (diagrams included)

AI Thread Summary
The discussion revolves around solving an electric circuit problem involving the brightness of lamps c, d, g, and h. The user is struggling to determine the brightness of these lamps relative to an original lamp and considers redrawing the circuit for clarity. A hint suggests that if lamp c and its mirror image have normal brightness, then the voltage across lamp d is 0V, indicating that lamp d is off. Participants encourage the user to explore different scenarios, such as removing lamps g and h, to better understand the circuit dynamics. Overall, the focus is on collaborative problem-solving and critical thinking in circuit analysis.

Homework Statement

Basically I need to find the brightness of the labelled lamps relative to the original lamp.

It is lamps c&d and g&h which are causing me the most trouble. Can anyone tell me what I should be looking for? I think redrawing the curcuit would be a good idea but I can't even do that.


Any help would be much appreciated.

Hint on c&d -- if c and its mirror image have normal brightness, what is the voltage across d?
 
Oh yeah it would be 0v so the bulb d is off


Any ideas on g and h?

Sure. But we want to hear your thinking about it -- that's what's important.

Poke at the problem some. What if g and its twin weren't there? What if h wasn't there? What are your thoughts about how to combine those two situations...?
 

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...
