Consider the full-wave rectified sinusoidal current in Table 17.3. Assume that the current is passed through a 1- Ω resistor.
(a) Find the average power absorbed by the resistor.
(b) Obtain cn for n = 1, 2, 3, and 4.
(c) What fraction of the total power is carried by the dc component?
(d) What fraction of the total power is carried by the second harmonic (n = 2)?
