hello,

Help me to answer these questions:
Give the physical meaning of Maxwell equations (equations in the general case).

div D=ρ
div B=0
rotE=-∂B/∂t
rotH=∂D/∂t+J

i have second question:
What is the difference between conduction current and displacement current?
thankyou

Well, let's start with the physical meaning of the displacement and the operational effect of the divergence. What do you think of those two?
 
displacement current does not
obey ohm's law

i do not have any ideas
 
Truth be told, I don't see why you're not using the definition with E instead of D. What does the divergence of a field tell you about that field?
 
the electric field
