Continuity of the first Maxwell equation.

In summary, the conversation discusses the proof of the continuity of the first Maxwell equation. It is noted that the y components of the E-field are ambiguous and only the parallel component (parallel to the surface) is continuous. The person asking for confirmation on the validity of the proof is advised to define the y component as the parallel one.

Suppose that we will proof the continuity of the first maxwell equation:

So we have [tex]div(\vec{E})=\frac{1}{\epsilon _0} \rho [/tex] than [tex]\iiint \ div(\vec{E}) = \oint_v \vec{E} d\vec{s}=\iiint \frac{1}{\epsilon _0 } \rho [/tex]
than follewed [tex]E_{y1} l -E_{y2}l=Q [/tex]

Therefore E must continue is this a good proof? Thanks.

You have not defined what "y" direction is. So your y components are ambiguous.

Only the parallel component of the E-field (parallel to the surface) is continuous.

Thanks if I define my y component as the parallel one. Is than the proof oké?
 

1. What is the first Maxwell equation?

The first Maxwell equation, also known as Gauss's law, states that the electric flux through any closed surface is equal to the enclosed charge divided by the permittivity of the medium.

2. Why is continuity of the first Maxwell equation important?

Continuity of the first Maxwell equation is important because it ensures that the amount of charge entering or leaving a closed surface is equal to the change in electric flux through that surface. This allows us to accurately predict and understand the behavior of electric fields.

3. How is continuity of the first Maxwell equation related to conservation of charge?

Continuity of the first Maxwell equation is closely related to the principle of conservation of charge. This principle states that charge cannot be created or destroyed, only transferred or redistributed. The continuity equation ensures that the amount of charge entering a closed surface is equal to the amount leaving, thus maintaining the total amount of charge in the system.

4. Can the first Maxwell equation be applied to all types of surfaces?

Yes, the first Maxwell equation can be applied to any type of closed surface, regardless of its shape or size. This is because the equation is based on the fundamental properties of electric fields, rather than specific surface characteristics.

5. How does the first Maxwell equation contribute to our understanding of electricity and magnetism?

The first Maxwell equation, along with the other three Maxwell equations, provides a comprehensive mathematical framework for understanding and predicting the behavior of electric and magnetic fields. It allows us to make accurate calculations and predictions about the behavior of these fields, which has numerous practical applications in technology and engineering.
