Hello,
Thank you for your reply.
So what exactly is the difference between electromagnetic radiation and domestic household electricity ?? is it just the presence of charge carrying particles commandeered to move electromagnetic energy from one place to another ??
People on this forum (...
Hello,
I have come to the understanding the one form of electrical energy is electromagnetic energy.
Suppose i have a photon stream
(a) How do i find out the voltage and current of the photons in the stream ??
(b)Suppose i have a photon stream whose voltage is V and current is I. If i...
Hello i got another doubt,
If electricity is electromagnetic energy, what is the need for photovoltaic ??
Cant sunlight for example be used directly as electricity ??
Sorry for bringing it up again, but could you please clear this confusion
So "electricity" is not electromagnetic wave but it is electromagnetic energy ??
@mfb and @nsaspook : thanks for the reply.
Quoting from http://www.capturedlightning.com/frames/Non-Herzian_Waves.html
"but one particularly useful consequence is the tendency of long thin conductors to guide an EM wave along themselves. When an EM field is guided in this way, we call it...
My confusion started because of the following lines in a textbook i am reading (skilling - fundamentals of electric waves) where there is quote along the lines of
"circuit theory may be considered as a special case of more general theory of electromagnetic fields" from page numbered 1.
[SOLVED] how to build a device to measure in angstroms
Hello,
I was looking at a micrometer and wondered how one could build a similar device for meauring in angstroms. Could someone point to some theory that discusses the same ( for example if i have to forge a screw what would be its...
Hello,
Are longitudinal EM waves ( I know they exist) any different from linearly polarised waves we learn about in antennae theory
Just to be clear http://www.antenna-theory.com/basics/polarization.php defines linear polarisation pretty clearly in the context i am talking about
@ Mikey thanks for the reply, i have some more questions.
But both are quantified by photons ??
What are the practical implication of "there can't be magnetic monopoles" on both electric and magnetic fields existing in a manner in which they can't be separated.
Instead of saying a body has X amount of mechanical energy why do people say it has nx Potential energy and (1-nx) Kinetic energy or viceversa.
Arent electric and magnetic forces the same ( i remember reading that they are like 2 sides of the same coin).

Hello thanks to both for the answers.
So the main point here being analysys and duality ??
So induction is how energy transfer occurs ( even in static electric fields ??) so if induction helps in energy transfer then why the need for both electric and magnetic fields ( all this time i had...
Hello,
Firstly i am new here ( not offering an excuse) and an on and off lurker to this awesome forum. I am trying my best to fit into the established rules ,sorry if i broke any inadvertently.
If kinetic and potential energy represent the same things why are there entities representing the...
