    Theorem
Click For Summary
The discussion focuses on the application of Thevenin's and Norton's theorems in simplifying circuit analysis for homework problems. Thevenin's theorem is used to find the equivalent circuit between two points, making it easier to analyze load characteristics when changing load resistance. Norton’s theorem provides a current source equivalent, which simplifies the calculation of current through the load. Participants emphasize the importance of using diagrams to illustrate these concepts clearly. Understanding these theorems is crucial for effective circuit analysis.

Hi all, Hope everyone is fine and dandy!

I am having real problems with my homework, it is based on thevenins and nortons theorem. please see the attached word document for the questions.
I understand on the first question that the circuit is divided into two before calculating the voltage and resitances. please can you provide explanations with diagrams on how this is done.

Any Help much appreciated! Thankyou!

What is your question?

For the first problem you would find the thevenin equivalent between A and B, so that when you change the load resistance the characteristics of the load will be easier to calculate.

For the second problem you merely use the norton equivalent so that you have a current source, and can calculate the current through the load easily.
 

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
