Refer to Problem 9.38 and assume a load voltage waveform as shown in Figure P9.40. Also assume:
|io|avg = 60 mA |vo|avg = 5 V |Vripple| = 5%
vline = 170 cos(?t) V ? = 377 rad/s
Determine:
a. The turns ratio n.
b. The capacitor C.
Problem 9.38
In the full-wave power supply shown in Figure P9.38 the silicon diodes are 1N4001 with a rated peak reverse voltage of 25 V.
n = 0.05883
C = 80 ?F Ro = 1 k?
vline = 170 cos(377t) V
a. Determine the actual peak reverse voltage across each diode.
b. Explain why these diodes are or are not suitable for the specifications given.
Referring to the following figure, technician A says that a shorted to ground circuit between the park light switch and the right front park lamp would likely cause all park lamps shown to not illuminate. Technician B says that if the fuses supplying the stop light switch and the turn signal flasher are both blown, this most likely indicates a short to ground between terminal 4 and the left front lamp or between terminal 6 and the right front lamp. Who is correct?
A. A only B. B only C. Both A and B D. Neither A nor B
State University tuition and fees can be paid using one of two plans. Early-bird: Pay total amount due one year in advance and get a 10% discount. On-time: Pay total amount due when classes start.
If the cost of tuition and fees is $20,000 per year, (a) how much is paid in the early-bird plan, and (b) at an interest rate of 6% per year, what is the equivalent amount of the savings compared to paying when classes start, that is, 1 year later than the early-bird plan?
