I fully understand mathematically using differential equations and also using conservation of energy why current should decay in an RL circuit.
However , I cannot comprehend how this phenomenon can be explained purely based on induced voltages and currents. An intuitive understanding basically...
Just take the projection of the rectangular plate along the plane perpendicular to the axis of rotation. And now find the MOI of the projection using regular techniques. That will give you the MOI.
This works because displacing any component of a system of particles , parallel to the axis ...
During current flow , electrons are certainly being accelerated and decelerated betweeen two successive collisions with the metal lattice. Since accelerated charge generates EM waves , why doesn't a DC current emit EMR?
I was just thinking about a problem for fun where
n layers of tape of thickness t are wound on a spool of inner radius r
and one needs to find the the variation of angular speed of spool as a function of time such that tape is obtained at a constant time rate v.
But , my question is ...
I have been trying to find the norton equivalent of a wheatstone bridge with the "bridge" resistor as a the load. The Bridge is unbalanced.
How do i find the current through the load when it is shorted to find the norton current?
It seems easy , but i haven't found any ways of doing it.
I...
I'm conducting a seminar at college on application of AC to passive components.
To Demonstrate what inductive reactance is , i want to wind a coil , connect it to a DC source , find the resistance. Then i want to directly connect it the AC mains and find th effective resistance again and show...
In my math exam , this question had appeared :

I'm having confusion as to what the answer to the question is.
I feel that the correct answer to the question would be 2 Direct common...
This is not anything related to geometry.
what AUmathtutor says is what i mean to convey.
Any tips on solving these?
And can you point me to any links which give some help?
I found a lot of stuff for trig , but none at all for algebraic identities. :(
I am learning how to prove conditional identities like
(a^2-c^2+b^2+2ab)/(c^2-a^2+b^2+2bc) = (s-c)(s-a)
if a+b+c = 2s
- Derived from Herons formula
I have understood the proof for the above , but i want more problems to work on.
Can anyone suggest some link where i can find similar...
After seeing contradictory posts on many forums , and getting differing opinions from my teachers , I'm completely lost with the ohms law...
I have a number of questions. Can someone please answer them for me?
1) Do semiconductors obey Ohms law? and why do they obey/not obey?
if they obey...
