Independence of Currents in Inductor-Switch Circuit

Click For Summary

Discussion Overview

The discussion revolves around the independence of currents in an inductor-switch circuit, specifically addressing whether the currents in two meshes, I1 and I2, are independent of each other when a switch is closed. The scope includes conceptual reasoning and circuit analysis.

Discussion Character

  • Debate/contested, Conceptual clarification

Main Points Raised

  • One participant questions whether the currents I1 and I2 are independent or dependent, seeking clarification on the conditions that would affect their independence.
  • Another participant suggests that the currents may be independent because the voltage across the short circuit is zero, but notes that a solution indicates I2 depends on I1, expressing confusion about this relationship.
  • A further contribution raises the point that both currents flow through the same element, questioning whether this connection implies a dependency between them.

Areas of Agreement / Disagreement

Participants express differing views on the independence of the currents, with some arguing for independence based on voltage considerations, while others highlight the shared element as a potential source of dependency. The discussion remains unresolved.

Contextual Notes

Participants do not fully explore the implications of circuit elements or the specific configurations that may affect current relationships, leaving assumptions about circuit behavior unaddressed.

If I closed the switch "s"
Are the currents in mesh "I1" and "I2" independent of each other? if yes Why /why not?
Thanks.

Well, what do you think would make them independent or dependent?

I think they will be independent because ΔV on the short circuit will be 0 but at (b) here

solution made I2 depends on 1 and I don't know why

How about the fact that they both flow through the same element? Does that not connect them in some way? Or put another way, are the two currents totally isolated from each other?
