Diodes and Applications - Technical MCQs
Q1: If the frequency of the applied ac signal to a half-wave rectifier is 60 Hz, the frequency of the pulsating dc output will beA
30 pps
B
60 pps
C
90 pps
D
120 pps
ANS:B - 60 pps The frequency of the output voltage is equal to the frequency of the applied ac signal since there is one pulse out for each cycle of the ac input (60 Hz). Therefore output dc pulsating voltage contains 60pps (pulse per sec). |
