Calculating RC-Constant of Coaxial Cable

AI Thread Summary
To calculate the RC constant of a coaxial cable, it is important to use half of the measured resistance value. This is due to the behavior of electrons within the cable, where the effective resistance encountered during charging and discharging is halved. Understanding this concept is crucial for accurate calculations in experiments involving coaxial cables. Clarification on the relationship between resistance and electron flow can enhance comprehension of the RC constant. Proper application of these principles is essential for successful experimentation.

Hi,

I am doing an experiment with a coaxial cable and i want to Count out it expected RC-constant for the cable.

I have measured the resistance for the cable, but when i count the RC, the resistansen that will be used only is the half of it resistans measured in the beginning.

Why should i use the half resistance?

Additional Details

I think it has something to do with the electrons, or?

Isn´t there anyone who can explain this?
 
I'm sorry, but I can't even understand what you're saying.

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...
