AI Thread Summary
To model stray capacitance in JFET amplifiers for mid-band frequencies, a small signal model is required. The capacitors in the circuit are treated as short circuits. It is suggested to seek foundational knowledge through textbooks or online resources, such as videos on JFET small signal models. Engaging with the material and attempting a solution before asking for help can lead to more effective guidance. Understanding the basics of small signal analysis is crucial for accurately modeling stray capacitance.

Homework Statement


Hello , I need to make a small signal model for mid band frequencies for the circuit I provided below.
I am also supposed to observe the "stray capacitance " in the transistor using this small signal model.


Homework Equations





The Attempt at a Solution



I know that the capacitors here act as short circuit.
The problem is I don't know where to start and what to do. I tried googling small signal model but I couldn't understand a thing.

Help will be greatly appreciated. Thanks.

Sounds like you need some more background. Is your textbook not providing the proper foundations? Youtube "JFET small signal model" and you will find a very good video posted by tarbidan that should help you get started.

BTW, welcome to PF. In order for us to provide the best kind of help, you should attempt a solution and ask specific questions.
 

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...
