Resistance series and parallel

Click For Summary
The discussion focuses on identifying resistors in series and parallel configurations in a circuit. Participants confirm that R1, R2, and R3 are in parallel, along with the branches (R5+R8), R9, and (R10+R4). R7 is clarified to be in series with a voltage source, indicating it is not parallel to any other resistor. The criteria for series connections are explained, emphasizing that current flowing through one resistor must also flow through the other. Understanding these configurations is essential for solving the circuit problem effectively.

Homework Equations



series - Ra+Rb

parallel - 1/[(1/Ra)+(1/Rb)]

The Attempt at a Solution



Im positive that R1,R2 y R3 are parallel, but also (R5+R8), R9 and (R10+R4) right? is R7 parallel to anything? which ones would be series? so confusing... thankies :]

Yes

These 3 branches are parallel branches.
is R7 parallel to anything?
R7 is not. It is in series with a voltage source.
which ones would be series? so confusing..
Two branches are in series if [all of] the current that flows through one also then flows through the other.
 

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?
