Repeat Prob. 3.104 if the full-wave bridge circuit is used instead of the rectifier in Fig. P3.104. Draw the circuit!
Problem 3.104
Simulate the AM demodulator in the EIA on page 122. Compare the spectra of the voltages across the two capacitors. The full-wave rectifier in Fig. P3.104 is operating at a frequency of 60 Hz, and the rms value of the transformer output voltage is 18 V.
(a) What is the value of the dc output voltage if the diode voltage drop is 1 V?
(b) What is the minimum value of C required to maintain the ripple voltage to less than 0.25 V if R = 0.5 Ω?
(c) What is the PIV rating of the diode in this circuit?
(d) What is the surge current when power is first applied?
(e) What is the amplitude of the repetitive current in the diode?
Can the real interest rate ever be negative? Under what circumstances can it be negative? If so, why not just hold cash instead of bonds?
What is the firm's marginal revenue at each positive rate of output Its average revenue d. What can you say about the relationship between marginal revenue and marginal cost for output rates below the profit-maximizing (or loss-minimizing) rate
