What factors affect the induced voltage in an induction circuit?

Click For Summary

Discussion Overview

The discussion revolves around the factors affecting induced voltage in an induction circuit, specifically in the context of a parallel RL circuit. Participants explore how changes in circuit components, such as an inductor opening, influence voltage behavior.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants suggest that the voltage remains constant regardless of load, particularly when a voltage generator is involved.
  • Others argue that the induced voltage across the inductor depends on the rate of change of current, highlighting the need for more information about the circuit configuration.
  • A participant notes that if the inductor were considered perfect, it would theoretically have zero resistance, leading to infinite standing current and induced voltage, but this scenario is contingent on assumptions about the inductor's properties.
  • There is a request for a diagram to clarify the circuit setup and facilitate a better understanding of the problem being posed.

Areas of Agreement / Disagreement

Participants do not reach a consensus; multiple competing views regarding the behavior of induced voltage in the circuit remain unresolved.

Contextual Notes

The discussion lacks specific details about circuit parameters and configurations, which may affect the conclusions drawn. Assumptions about the ideality of components are not universally accepted.

TL;DR
In a 2 Branch parallel r l circuit what would the voltage across the branch 2 to do if the inductor in branch 2 opens?
I'm thinking it would stay the same. Any answers?

Do you have a diagram to help us figure out what you are asking about? Is this for schoolwork?

Assuming a voltage generator, the voltage stays the same irrespective of load.

The induced voltage across the L will depend on the rate of change of current. There's not enough information to know that unless you assume that the Inductor is perfect. If it is perfect then it resistance would be zero so the standing current would be infinite and the induced voltage would be infinite too.
So your circuit description doesn't give us a possible answer - a diagram may help resolve this.
