palaphys replied to the thread Spherical capacitor RC system -- determine steady state charges.sorry, long time but I feel I've tried enough. not getting how to proceed. trying to use V=Q/C -
palaphys replied to the thread Current through shorted branch -- clarification.the correct answer is for voltage at t=0+ is -E.

Like.
The larger question does not matter for the OP question. As you already figured out, it was just a matter of comparing two different... -
palaphys replied to the thread Current through shorted branch -- clarification.also, to be precise the source is a Youtube video, which uses the incorrect polarity. thanks for pointing that out.

palaphys replied to the thread Current through shorted branch -- clarification.I think I have found my mistake. In this charging equation, I had to substitute ##i_{s.s} ## as -E/(2R) and not just E/2R . (As the...

palaphys replied to the thread Current through shorted branch -- clarification.I think there is some misunderstanding here. My original question posted here was a part of a larger question, which is the one...

palaphys replied to the thread Current through shorted branch -- clarification.okay let me post the larger part of the question here. this was the original circuit. I am required to find the voltage across the...

palaphys posted the thread Current through shorted branch -- clarification in Introductory Physics Homework Help.In this seemingly simple circuit, applying KCL, I get the current in the shorted branch as ## 3E/(2R) - 2E/(2R) = E/(2R) ## but some...

palaphys posted the thread Spherical capacitor RC system -- determine steady state charges in Introductory Physics Homework Help.This is the diagram given for the problem. Now I was able to identify, that the fact that the capacitance of a spherical capacitor, with...

palaphys replied to the thread Angular Momentum- Conserved or not?.ok that makes sense. but I have a question. IF there was no external torque (hypothetical) then is it valid to conserve momentum as I...

palaphys replied to the thread Angular Momentum- Conserved or not?.I have another question: If angular momentum is conserved, then it would be conserved in all directions. But in the horizontal...

palaphys posted the thread Angular Momentum- Conserved or not? in Introductory Physics Homework Help.Consider the diagram shown above. I came up with two ideas to solve this: i) I do not see any external torques about the vertical axis...

palaphys replied to the thread Irodov- 1.123- Simple conceptual question with two masses connected by a spring.so are you implying, that the value of F I got using force balance, IS a valid value for some a force to get the block moving? but it's...

palaphys replied to the thread Irodov- 1.123- Simple conceptual question with two masses connected by a spring.but when velocity is maximum, there is a momentary equilibrium, isn't it? this means forces at that point of time will be balanced. is...
