AI Thread Summary
The discussion revolves around the equation V1/V2=N1/N2, which relates the voltages and turns in a transformer. The original poster questions why the current is zero in their scenario. Participants point out that the primary coil is connected to a battery, which influences the current flow. The conversation emphasizes the importance of understanding transformer connections and their effects on current. Clarifying these connections is crucial for solving transformer-related problems.

The Attempt at a Solution



V1/V2=N1/N2, that means there shouldn't be a current. Why it is 0?
Thanks!

Look carefully at what is connected to the primary coil.
 
Sorry, but I didn't notice any difference...
 
It is a battery !
 
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 '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 .
