Phase differences in Transformers

Click For Summary

Discussion Overview

The discussion centers on the phase difference between the current in the primary coil and the induced electromotive force (e.m.f.) in the secondary coil of a transformer. Participants explore the concept of phase differences in the context of transformer operation, referencing educational materials.

Discussion Character

  • Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions the existence of a phase difference, asking for sources to support the claim.
  • Another participant asserts that there is indeed a phase difference of 90 degrees, referencing a specific question from an A Level physics exam mark scheme.
  • A link to the source of the claim is provided, which contains past exam papers.

Areas of Agreement / Disagreement

Participants do not reach a consensus; there are competing views regarding the existence and value of the phase difference.

Contextual Notes

The discussion references a specific educational context (A Level physics) and relies on the interpretation of exam materials, which may not encompass all theoretical perspectives on transformers.

How is the phase difference between the current in the primary coil and induced e.m.f. in the secondary coil be 90*??

What makes you think there is a phase difference? Do you have a link to your source?
 
Ofcourse.

Of course.

A Level, physics paper 4 summer 5 question no. 6. In the mark scheme it says 90 degrees.
