Between i1 = -3sin(100πt +60°) and i2 = 4cos(100πt - 30°), find the phase angle. Sketch and state which sinusoid is leading.

SHOW COMPLETE SOLUTION. A. Determine the phase shift between V(t) and I(t) in degrees and two decimal places. B. What must be the operating frequency of the source for V(t) and I(t) to be in phase? Use Hertz and two decimal places.

For the following pairs of sinusoids, determine which one LEADS by how much. (draw the phasor diagram)a. e = 10cos(2t - 21°)V and i = 5cos(2t - 11°)Ab. e = 20sin(ωt + 50°)V and i = 60cos(ωt - 10°)Ac. e = 311sin(250t + 120°)V and i = 15.5sin(250t - 165°)A

Add : V, = 30 cos (w t + 50°) Vz= 50 cos (wt -b0°) a. Per for m Vi +Vz =V and finally expre so V as signal b. Find v and write v in both forms of phasor a CoS
