Solved: An ac voltage source V = Vosi11^ + 90) is
Chapter , Problem 81(choose chapter or problem)
An ac voltage source V = Vosi11^ + 90) is connectedacross an inductor L and current I = 70 sin (cot) flows inthis circuit. Note that the current and source voltage are 90out of phase, (a) Directly calculate the average power deliveredby the source_over one period T of its sinusoidal cyclevia the integral P = J ^V I d t/T . (b) Apply the relationP = ^rms Kmscos 4> t this circuit and show that the answeryou obtain is consistent with that found in part (a).Comment on your results.
