How Do Series and Parallel Circuits Compare in Current, Power, and Voltage Drop?

Series circuits have lower current and higher voltage drops compared to parallel circuits, which allow for greater current flow and lower voltage drops across individual components. Power dissipation is greater in parallel circuits due to the higher current, while series circuits dissipate power based on the total resistance. Understanding these concepts relies on applying Ohm's Law (V = I*R) and the power equation (P = I*V). For graphing Potential Difference (V) against Upward Acceleration (m/s^2), the slope represents the relationship between these variables, while the x-intercept indicates the value of potential difference when acceleration is zero. Mastering these principles through theoretical understanding and practical problem-solving is essential.

I have some questions in comparing series and parallel circuits

Which circuits contain the greatest current?

Which circuits dissipate more power?

and which circuits have a larger voltage drop?

is there any way in figuring this out, by just theory or do the numbers intrepret these questions?

Also was wondering If i had a table of values of Potential Differece(V) and Upward Acceration (m/s^2) and was asked to graph this, what would the slope represent? and the significane of the x-intercept?

Thanks.

When you appreciate the underlying concepts of Ohm's Law V = I*R and the power equation P = I*V, you can answer this part yourself. Try some problems that do use numbers in both series and parallel circuits. After solving a few problems of each type, you will also be able to answer this question yourself.
 
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?
