Dear forum please help me with the following understanding: There is (are) such equipment Earth ground testers (https://www.fluke.com/en/products/electrical-testi...) - it is used to measure grounded electrical systems or to measure. Such equipment is having multiple poles that are attached to...

Dear willem2 and DaveE, Let me ask another question... "When you get far away from the conductor, it should look like the conductor had no effect. Like this:" When an initial charged (with charge +Q) plate creates an electric filed it originates from the charged surface and penetrates into...

Dear PF, I have a question regarding a conductor in electric filed. I have formulated my question in attached PDF file ... would please be so kind and advise me please... Thanks you in advance ...

Dear PF, I need to have a simple mini-camera with wire connection... (i don't want wireless transmission). if i get for example an ordinary small FPV camera...

Dear Forum Memebrs, Could you please advise if it is possible to think that in some instances the flow of fluid in P&ID diagram is similar to the flow of electrical current in circuit boards: in order to have an electric current you have to have a potential difference across two points (which...

Thanks Bill_K for you help... So is it (TT gauge) much the same as Coulomb gauge in vector field theory ? Thanks

I have a question about gauges in gravity. Symmetric tensor field in four dimensions has 10 independet components, when we want to describe massless spin-two field (graviton) we impose harmonic gauge which reduces 10 independet components to 6 and afterwards we use diff invariance and...

Could you please advise me how does one get the 5.4.10 matrix in the attached page from the "MOHAPATRA R.N. UNIFICATION AND SUPERSYMMETRY.. THE FRONTIERS" or what are those epsilons... Thank you

Dear PF, Could you please advise me good detailed reference on Grand Unified Theories... especially I want to see where for example SU5 potential is composed from two Higgs representations (two Higgs fields) and how symmetry breaking (minima of potential appears for both of fields) happens...

Could you pls advise me any reference (textbook for example) where I can find how to calculate maxima minima of function of several variables... or drop a couple of lines here.. Thank you

Dear PF, I am trying to draw some diagrams in jaxo draw, but I don't know how to assign Greek index whenever necessary, can you please advise me step by step... as i understand it is related to some "postscript" issues that i don't know how to set up ... would you be so kind and drop me a...

Dear PF, I am a little bit confused could you pls help me ... Suppose I a have a scatering or conversion of two particles via graviton propagator. Graviton propagator couples with energy-momentum tensor of matter fields. So can i assume that vertex to which graviton propagator is coupled...

Thank you Bob S for your reply... If the source is radioactive isotope then I guess only Crystal Bragg diffraction might be applicable . . . correct ?

Dear PF, Is is possible to focus somehow gamma radiation? Suppose d'like to intensify gamma rays and I want to focus it... is it possible to do it... ? Are there any materials that may "reflect" gamma rays.. to use as a "reflector" thus intensifying ... thank you

Just forgotten to mention (combination of fields) exactly the same . . . so identical field combinations in two vertex but different coupling strength . . .
