Where to find Electric displacement help

In summary, the conversation is about the concept of electric displacement fields and the confusion surrounding it. The speaker is looking for resources such as lectures or textbooks to better understand the topic, as their current textbook (Griffiths) does not provide sufficient explanation. The main issue is understanding the difference between electric displacement (D) and electric field in an electrostatic environment, particularly regarding how the field lines end at different types of charges. The speaker is open to receiving an explanation from the listener, but is unable to ask specific questions due to their limited understanding of the topic.

I'm having a little trouble wrapping my head around the idea of electric displacement fields, it doesn't fit in with any the intuition I gained from lower devision E&M. Are there any lectures online dealing with the subject? Or textbooks that do a particularly good job of explaining? (My class uses Griffiths, who I'm usually pretty happy with, but his explanation of the topic isn't sufficient this time).

To clarify: my issue is with the difference between electric displacement (D), and the closest analogy I know, electric field, in an electrostatic environment. Things like how E field lines end at any charge and D lines only end at free charges. If you want to explain it yourself that would be helpful as well, but since I have a weak understanding I cannot form pointed questions that can be answered easily.
 

FAQ: Where to find Electric displacement help

What is electric displacement and why is it important?

Electric displacement, represented by the symbol D, is a measure of the electric field inside a material that is not affected by the presence of free charges. It is important because it helps us understand the behavior of electric fields in different materials and is a key concept in the study of electromagnetism.

2. How is electric displacement related to electric flux?

Electric displacement is related to electric flux through the equation D = εE, where ε is the permittivity of the material and E is the electric field. This equation shows that electric displacement is directly proportional to electric flux and helps us understand the behavior of electric fields in different materials.

3. Where can I find resources for help with understanding electric displacement?

There are many resources available for understanding electric displacement, including textbooks, online tutorials and videos, and academic websites. Your local library or university may also have resources available for you to use.

4. How can I calculate electric displacement for a given material?

To calculate electric displacement for a given material, you will need to know the permittivity of the material and the electric field strength inside the material. You can then use the equation D = εE to calculate the electric displacement.

5. How does electric displacement differ from electric field?

Electric displacement and electric field are related but different concepts. Electric field is a measure of the force experienced by a charged particle in the presence of other charged particles, while electric displacement is a measure of the electric field inside a material. Electric displacement is not affected by the presence of free charges, while electric field is.
