AI Thread Summary
The discussion centers on the phase difference of 90 degrees between the primary coil current and the induced e.m.f. in the secondary coil of transformers. A participant references a specific A Level physics exam question that confirms this phase difference. The source of the information is linked for verification. The conversation emphasizes the importance of understanding this concept in transformer operation. Overall, the phase difference is confirmed as a key point in the context of electrical engineering principles.

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

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

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
i want to just test a linear generator with galvanometer , the magnet is N28 and the wire (Cu) is of 0.6mm thikness and 10m long , but galvanometer dont show anthing ,
The core is PLA material (3d printed)
The magnet size if 28mm * 10mm * 5mm
If the universe is fundamentally probabilistic, and all possible outcomes are realized in some branch of the multiverse, does that invalidate the concept of scientific inquiry? If knowledge is merely a description of one particular branch of reality, does it have any inherent value?
