Which of the following is not equivalent for the following A

Which of the following is not equivalent for the following AC signal. i(t) = Acos(wt)? A certain power supply generates an AC voltage signal that earn be characterized as the cosine function v(f) = V_m cos (w t + theta) having a frequency of 13.56 [Hz]. If the power supply delivers a maximum power of 300 |w| to a 5 [ohm] resistor and the AC voltage signal reaches a maximum value at time t=21.15 (ms), calculate Vm. w, and theta for the voltage signal.

Solution

1) c.
