In a resistor v and i are always out of phase

WebIn a purely resistive circuit, all circuit power is dissipated by the resistor (s). Voltage and current are in phase with each other. In a purely reactive circuit, no circuit power is dissipated by the load (s). Rather, power is alternately absorbed from and returned to the AC source. Voltage and current are 90° out of phase with each other. 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).

WebIf they are “in-phase” that is, there is no phase shift then they can be added together in the same way as DC values to find the algebraic sum of the two vectors. For example, if two voltages of say 50 volts and 25 volts respectively are together “in-phase”, they will add or sum together to form one voltage of 75 volts (50 + 25). WebAug 8, 2016 · In general, if you define either v or i to be sinusoidal, the other will follow along and be sinusoidal, too.
