Hello guys
My question is simple but it really bugs me! Why we must define a torque about a POINT? In most of the textbooks i checked they define torque about an Axis. In wikipwdia though it is defined about a point. As a matter of fact it mentions:
"Torque is defined about a point not...
PV diagrams for heat engines are "legitimate"?
Hello forum
Since my student days i was wondering about how is it possible to represent the cycle of the gas in a heat engine (e.g. otto cycle) in a PV or whatever diagram when it is obvious that the gas is not in equilibrium during the process...
what you explained in your second paragrapgh (faradays law, induced electric field, work done on free electrons e.t.c) i have mentioned in my first post also. Which means that i am already aware of all that. You suggest me to consider both forces and correlate them. Well that is my question from...
Yes Philip
I do understand your explanations very well and i know that the results are unquestionable. But i am taking this different microscopic approach on explaining what happens. It is something that i always try to do when dealing with a phenomenon. This bugs me for a lot of time! Maybe...
hi f9toli
I don't get it when you say that the current has nothing to do with the electrons drift velocity. From what i know it is proportional to the current. I know that viewing a circuit at a microscopic level (electrons) is not the most efficient way but then again it is something i need to...
Hey Philip
The analogy is always helpful and i am aware of it. But it doesn't give a realistic explanation of why the drift velocity of the electrons maximizes when the capacitor is discharged. I am still in dark.
Thanks anyway

Thanks for the reply Philip.
I am aware of the approach, you are essentially using the first Kirchoff rule which is based on thw conservation of the charge. I need an explanation of what happens dynamically. Why the electrons reach their maximum drift velocity when the capacitor is discharged?
Hello guys
This is my first post and i am glad to be a member of this forum. There is something bugging me for a lot of time. I have a problem understanding why the current of an LC oscilator circuit is maximized when the capacitor is fully discharged. Of course when it is explained from the...
