    Current Junction
AI Thread Summary
The discussion centers on determining the current in a wire above a junction in an electrical circuit. The user expresses confusion regarding the term "above the junction" and struggles with applying the correct formulas, specifically Ohm's Law (V=IR). Attempts to calculate the current by adding voltages and resistors have been unsuccessful. The user also questions the relevance of Kirchhoff's Current Law in this context. Clarification on these concepts is needed to solve the problem correctly.

Homework Statement



In the figure, what is the current in the wire above the junction?


Homework Equations



V=IR or I=V/R

The Attempt at a Solution


I am really confused as to what "above the junction" means. I tried to add the voltages and add the resistors and divide them to get the current and it didn't work. Then I tried to just do the top voltage and resistor (so it would be three) and that didn't work either. What am I doing wrong?

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...

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...
