Sinor and Phasor Diagramme?

[lord loh.]

What is Phasor and Sinor diagramme? What are they plotted agsinst? And how to interpret them?

I have sample pic from my text book.

Looks like a phasor diagram to me.

Many years ago, when Marconi was a boy, there were vector diagrams which could be considered either as an X-Y plot or a polar coordinate plot of some electrical quantity.
Then someone decided that boring old vector diagrams were just not the thing to have anymore, we would have phasor diagrams, just the same as a vector diagram but change the name to confuse the students.
It looks like we now have sinor diagrams, maybe so that people do not confuse them with a futuristic beam energy weapon from a popular science fiction series (Beam me up Scotty).

:lol: :lol: :lol: :lol: :lol: But I still have to live with sinor and Phasor diagrammes. Can't tell my school people that is is nonsense.

But why do you call it Phasor and not sinor? The picture from the text book I mean.

Probably because I never heared of a sinor until this morning!

Same here!, never heard of it - they used to be called vectors, then they changed to phasors.

A copy of this post at Physics Forums. There does exist a Sinor diagramme as well. :?
