Kirchoff's Law: Identifying Loops in Circuits

Click For Summary
Identifying loops in circuits using Kirchhoff's Law can be challenging, particularly with multiple loops present. In the provided diagrams, the loops for the first diagram are correctly identified as ABCFA and ABCDEFA, while the second diagram's loops are ABCFA and CDEFC. Understanding the structure of the circuit is crucial for accurate loop identification. Clear labeling and visualization of the circuit can aid in this process. Mastery of these concepts is essential for solving circuit problems effectively.

Homework Statement



I am doing Kirchoff's law and i have problems in identifying different loops in a circuit, especially multiple loops. For example, in my attachment for diagram 1, there are 2 loops(ABCFA and ABCDEFA) ? But for diagram 2, the loops are ABCFA and CDEFC?

The loops for 1 and 2 are correct.

Thank you!
 
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?
