I want to learn about adding harmonics to the fundamental and calculating lag. I also have to find the voltage after 20milliseconds by simulation and

__calculating.__

what would this come under. I know its not phasor diagrams as they only work on one frequency. I have three, the fundamental third and fifth harmonics. the fifth I have to add a lag to, graph and show voltages. then calculate the voltage after 20milliseconds.

do I use Vsin(wt+a)?

voltage for the fundamental would be 100v

w would be 2*pi*50

then add "a"? on my excel graph I have "a" as time. I found the periodic time of the first wave which was 1/50 = 0.02seconds. then I broke that up so the graph had from 0 up to 0.02

form what I have read on some sites the "a" is an angle?

any help would be great, a website that showed how to calculate the lag

thanks
