AI Thread Summary
The discussion focuses on the behavior of current in an RL circuit when a switch is opened and closed. Initially, the switch is closed at t = 0, and the current through R1 can be calculated using the given voltage and resistances. After a long time with the switch closed, the current stabilizes through both R1 and R2. When the switch is opened, the current through R11 is questioned, with the assumption that it would be zero, which is incorrect. The conversation emphasizes understanding current flow dynamics in response to switch positions in RL circuits.

The switch in the figure is open for a very long time and then closed at t = 0. What is the current through R1 immediately after the switch is closed? ( Use V = 3.5 V, R1 = 848 , R2 = 548 , L = 7.2 mH )
After the switch has been closed for a long time what is the current through R1?
After the switch has been closed for a long time what is the current through R2?

Hi Havoc0040. Welcome to Physics Forums.

What is your question about this problem? What have you already tried?
 
sorry i was able to figure this one out

The switch is now opened. What is the current through R11 immediately after the switch is opened? this is my question i thought it was 0 but that's not right
 

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...
