Magnitudes and Directions of Currents in Resistor

AI Thread Summary
The discussion focuses on understanding the flow of current in a circuit involving resistors and batteries, specifically at the juncture of R2. The user expresses confusion about the current paths after initially determining their direction based on battery placement. They mention applying Kirchhoff's law but struggle with the subsequent current behavior at the junction. The conversation emphasizes the importance of visualizing current flow and correctly applying circuit laws to resolve ambiguities. Clarifying these concepts is essential for solving the homework problem effectively.

Show your attempts. Apply Kirchhoff law.
 
I don't understand where the current is flowing. I've drawn where I think they go, based on the position of the batteries, but I am confused about where they go after this because they both seem to have the current meet up at the R2 juncture...

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
