Thanks for the answer.Can you elaborate your answer?After the connection,how does surface charge density vary?(There exist already established electric field, whose value is zero outside the capacitor )
Ok,so a current carrying conductor produces both Electric Field and magnetic field.If that correct, can I think like as follows?
In a current carrying conductor ,charges ( electrons)are moving with respect to the lab frame.since the length contraction happens ,negative charge per unit length is...
I answered that question by considering like spheres of charge located at 3 corners(assumed equal charges on 3 spheres). I ignored everything as you said for the answer.
But how does that electric field produce?How can I solve that question by treated those lines like spheres of stationary...
So current carrying conductor produces both Electric Field (due to surface charge) and Magnetic Field?
Then why is surface charge creation happening while current flowing through a conductor?
I think if current flowing through a conductor then electric field will not be produced because there is...
If those are charged spheres ,I don't have any confusion.but here those lines are current carrying conductors and at the same potential.
If I keep a test charge near a current carrying conductor will it exert a force?
If I keep a test charge in between two current carrying conductor of different...
Does static charge near to a constant current carrying conductor experience force on it?
I am asking this question because i have learned that electric field and mangnetic field are same thing but viewing differently with respect to the frame of reference...when a positive test charge moves (...
Sir,
So permeability was defined before Permittivity?
From ampere's force per unit length f∝i*i/r
In cgs system they chose proportionality constant as 2( i don't know why)
So f per length=2ii/r
Inorder to simplify ampere's law 1/2π was included but they chose same unit of current in the SI...
Sir..but why did they choose a strange number as Permittivity? Even though in SI system we can use Permittivity as unity ( like in HLU) that makes equation simpler. By this we can define one coulomb of charge accordingly.there would be a specific reason for this strange value, right?
I know...
But how to get the value of ε0 as 8.85*10^-12 by converting heaviside-lorentz units into si unit?? In HLU mass is in gram , length in cm time in s.if we convert that units into kg,m then we will get the factor of 10^-9...so that unit of charge is not same for both...can u derive the value of ε0...
