This is a problem from my midterm that i'm trying to understand before my final. The question is; A voltage phasor is given by V = 12∠70° and the frequency is 60 Hz. What is the time-domain voltage at t = 1 ms? a. 1.47 V b. 5.11 V c. -0.335 V d. -4.73 V As far as i know, the only equation relevant to this is V(t) = Vmax*sin(ωt + φ). When i plug in the values, V(t = 0.001) = 12 sin(120π(0.001) + 7π/18), i get V = 12(0.9996), which does not match any of the possible results. What am i getting wrong?
