AI Thread Summary
R1, R2, and the capacitor are confirmed to be in parallel, while R3 is not. The necessary condition for components to be in parallel is that they must share the same voltage across them. The discussion revolves around clarifying the configuration of these components in a circuit. Understanding the arrangement helps in analyzing current flow and voltage distribution. The distinction between R3 and the other components is crucial for solving circuit problems accurately.

The Attempt at a Solution


This was a conceptual question about currents I got it correct. Just for my knowledge I was wondering if R3,R1,R2, and the capacitor were all in parallel. I know R1,R2, and the capacitor are definitely all in parallel but I wasn't sure if R3 also was?

What is the necessary condition for parallel components?
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
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...
