The voltage across a 200- \(\Omega\) resistor is given by the \(a_{n}\) Fourier coefficients shown in volts in Figure P13=3o . All \(b n\) coefficients are zero, as is \(a_{0}\). The fundamental frequency is \(500 \pi \mathrm{rad} / \mathrm{s}\).
(a) Find expressions for the current through the resistor and the power dissipated by the resistor.
(b) Find the average of the power expression by integrating over one period of the waveform and dividing by the period.
