RLC circuit, need some help with the intuition behind inductors.

AI Thread Summary
The discussion centers on confusion regarding the behavior of an inductor in an RLC circuit, specifically why a voltmeter (V2) reads 0 volts immediately after a switch is closed. The user questions whether the inductor's induced electromotive force (emf) would cause a negative reading instead. Clarification is provided that the induced current opposes the initial current, preventing voltage from registering across the voltmeter at that moment. The conversation emphasizes the need for a deeper understanding of circuit dynamics, particularly the role of inductors in opposing changes in current. Overall, the key takeaway is that the voltmeter reads zero due to the inductor's immediate response to the change in current.

Homework Statement


I attached a picture of a sample problem that I was confused about. What I don't understand is why the V2 voltmeter would read 0 volts (according to the answer key). This is because I thought that an inductor produces an induced emf and current. So wouldn't the voltmeter read a negative value instead of zero?

Edit: immediately after the switch is closed.

Are they asking about when the switch is off?

Oops, immediately after the switch is closed.
 
I am very weak at circuits and I wish my physics II teacher could gives us better insight to this stuff, however, here is a thought: Initial charge goes from high potential, but when it hits the inductor, the induced current is supposed to oppose it right? So, it never actually gets through that part of the circuit and so the voltage does read anything it goes through it right? I mean, can you back me up on this one if you feel this is completely wrong?

The voltmeter will not read negative.

What are your answers for the other meters after the switch is closed? Explain your reasoning behind each answer.
 

Thread 'Rolling without slipping on a curved surface'

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...

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...
