WebUsing phasors to represent AC voltages The AC voltages across an AC power supply, an inductor, a capacitor, and a resistor, all connected ... zero-to-peak currents), is twice the actual average power. To correct for this, we use rms voltages and currents. The rms voltage is the zero-to-peak voltage divided by p 2 , and the rms current is the ... WebJun 19, 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 ...
