Maxwell's Capacitor argument for a time independent Current

Click For Summary
SUMMARY

The discussion centers on the concept of "time independent current" in relation to capacitors. Participants clarify that a constant current, which does not vary with time, is distinct from time-dependent currents such as AC current. The term "time independent current" may not be the most accurate descriptor, as it can lead to confusion. Understanding these distinctions is crucial for discussions on capacitor behavior in electrical circuits.

PREREQUISITES
  • Basic understanding of electrical circuits
  • Knowledge of capacitor functionality
  • Familiarity with AC and DC current concepts
  • Understanding of current as a function of time
NEXT STEPS
  • Research the behavior of capacitors under constant current conditions
  • Explore the differences between AC and DC currents in electrical engineering
  • Study the mathematical representation of time-dependent and time-independent currents
  • Learn about the implications of current types on circuit design and analysis
USEFUL FOR

Electrical engineering students, circuit designers, and anyone interested in the principles of current flow in capacitors.

Homework Statement
Why can't we apply the. Maxwells argument to a time independent Current applied to a capacitor, to conclude the existence of a displacement Current inside a capacitor?
Maxwells argument considered a pot like surface between the plates of a capacitor with its open end outside. And argued that since the current enclosed is 0, B must be 0 just inside the capacitor, which is not true.
Relevant Equations
Ampere Maxwell Law
Is it because the current applied to a capacitor will never be time independent? Please help me out🙏

Sorry, what is a "time independent current"? Can you define that, or give some examples?

What I meant was a constant current - one which is not a function of t. A time dependent current would be AC Current. I am not sure if the name time independent is correct.
