Hey people,

I'm struggling to understand exactly what Electric Flux Density

So far, my understanding is that

Can anyone help me out here?

I'm struggling to understand exactly what Electric Flux Density

**D**and Electric Field Intensity**E**are.So far, my understanding is that

**D**depends on relative permittivity, while**E**depends only on the permittivity of free space. Also, I understand that**D**reflects only the free charges, while**E**reflects both free and bound charges. Where I'm stuck though, is that my book also tells me that**D**is independent of the medium it is in, while**E**is dependent on the medium it is in. This just doesn't click with me, since the actual value of**E**doesn't change if you change the medium (and thus the relative permittivity), while the value of**D**does.Can anyone help me out here?
