Sorry if this seems fundamental, but if someone could give me their thoughts.
A Sinusoidal voltage of vt=[50 cos(ωt + 45) + 28.28 cos(ωt)] V is applied across a 5Ω resistor. the Average power (W) deliverd to the Resistor is most nearly?
I see, and can follow the solution, but dont understand the reasoning? Specifically what to do with the two components of the voltage.
