Currents

AI Thread Summary

The discussion centers on the inability to change the potential difference in household currents. It highlights that while household appliances often use transformers to adjust voltage, the overall household voltage remains constant to prevent hazards like fuse ignition from overheating. The example of a laptop operating at 19.5V from a 120V outlet illustrates this concept. The conversation emphasizes the importance of maintaining stable household voltage for safety and functionality. Understanding these principles is crucial for safe electrical usage in homes.

Voltages are changed on household appliances all the time through transformers. For example my laptop runs at 19.5V and the outlet outputs at 120V.

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 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

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...
