In a resistor v and i are always out of phase

WebAs with the resistor example, the power is also positive when the instantaneous current and voltage are both negative (below the line). However, because the current and voltage waves are 90° out of phase, there are times when one is positive while the other is negative, resulting in equally frequent occurrences of negative instantaneous power.

Power Triangle and Power Factor in AC Circuits

WebSince the current and the voltage both depend on time in an ac circuit, the instantaneous power p (t) = i (t) v (t) p (t) = i (t) v (t) is also time dependent. A plot of p(t) for various circuit elements is shown in Figure 15.16. For a resistor, i(t) and v(t) are in phase and therefore always have the same sign (see Figure 15.5).
