Question
The Maxwell’s equation (which is based Ampere’s law) for any conductor will be
Select one:
a. Curl(H) = J
b. Curl(E) = J
c. Curl(E) = Jd
d. Curl(H) = Jc
Solution
To determine the correct option regarding Maxwell's equations based on Ampere's law, we first need to clarify what Ampere's law states and how it fits into Maxwell's equations.
Understanding Maxwell's Equations and Ampere's Law
Maxwell's equations include four fundamental equations that describe how electric and magnetic fields interact. One of these equations, derived from Ampère's law, describes the relationship between the magnetic field (H) and the current density (J).
Ampère's law, including Maxwell's correction, states:
However, in a more simplified form, specifically in static or quasi-static conditions, this can be approximated to:
Evaluation of Options
Now, assessing the given options about the curl of the magnetic field () and the current density (), we find:
- Option a: Curl(H) = J - This aligns with the standard expression of Ampere's law for static situations.
- Option b: Curl(E) = J - This does not correctly represent any standard form of Maxwell's equations.
- Option c: Curl(E) = J - This is a repeat of option b and is incorrect.
- Option d: Curl(H) = Jc - The term "Jc" is not standard and is confusing without context.
Conclusion
The most accurate representation from Ampère's law in the context of Maxwell's equations is:
Final Answer
a. Curl(H) = J.
