Nettet7. apr. 2024 · In phasor, the sine wave is converted into cosine. Hence, the sine wave with an amplitude of 2 can be written as: 2 sin(ωt) = 2 cos (ωt-90). As this is a pure resistive circuit the impedance (Z) is pure resistance; therefore, Z = R, the imaginary part phase is 0, as it is the real value. Nettet19. jun. 2024 · Let us examine the two sinusoids, v1(t) = Vm sin ωt and v2(t) = Vm sin (ωt + ϕ) The starting point of v 2 occurs first in time. Therefore, we say that v 2 leads v 1 by ϕ or that v 1 lags v 2 by ϕ. If ϕ ≠ 0, we also say that v1 and v2 are out of phase. If ϕ = 0, then v1 and v2 are said to be in phase; they reach their minima and maxima ... flights psc buf

I'm not exactly sure why they do this. It is the same for Part B, why do they subtract pi/2. cherry\\u0027s trenton
