(I graphed it using degrees instead of radians, but it gives the same thing)

This shows that Ih is a sine wave that has been shifted slightly.

You could use that graph to estimate the amplitude and shift, or you could probably do it mathematically as well. Somehow.

]]>Q: Given that I=3*sin*wt and Ij=4*sin*(wt - pi/4)

1) We need to find Ih = I + Ij

and

2) By calculation find the resultant current Ih in the form:

Ih = A*sin(wt + a)
