Question
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
