Transcribed Image Text:Given Signals:
v = 10 cos(wt + 70°)V
vz = 6 cos (wt - 120°)V
U3 =
12 sin(wt + 120°)v
Which statement is correct?
1. vị leads v2 by 170° and leads v3 by 40°
2. vi lags vz by 170° and leads vz by 110°
3. v lags vy by 170° and leads vz by 40°
4. vi leads vz by 170° and lags vs by 110°
03 Write 1, 2, 3 or 4
04 Determine: Vr = Vì + V2 – V3 and write the final answer in polar form.
Question 4
Vr = 10270° + 6- 120° – 12230° = 10.1332 – 169.77°V
