Homework Statement
I am confused about how they got the expression:
VPcos(ωΔt)=VP-Vr
Specifically you can find the notes in page 5 of this article:
http://whites.sdsmt.edu/classes/ee320/notes/320Lecture8.pdf
You may also find it useful to refer to the graphs as a reference.
Shouldn't the expression be:
VPcos(ωT)-VPcos(ωtd)=VP-Vr
Since we want the voltage difference between the points td and T.
