Select the best answer for the question. 4. Look at the drawing shown in the figure above. When you see this drawing in a schematic diagram, you should recognize that it represents a/an O A. step-up transformer. O B. inverter. C. bridge rectifier. OD. thermal relay.

A single phase diode bridge rectifier is connected by a transformer to ac supply of 230 V, 50 Hz and it feeds a R-L load of lo = 10 A. Average power delivered to load will be (Take transformer turn ratio = 1)

Design a bridge rectifier circuit to provide an output of 100 VDc. Calculate the diodes PIV rating and the transformer's turns ratio, if power is taken from the 120 V line AC supply. ***Type the letter of the correct answer. 1. The diodes PIV rating is: a. 157.23 V b. 222.36 V c. 314.47 V d. 111.18 V 2. The transformer's turns ratio is: a. 0.3816 b. 1.0793 c. 0.7632 d. 0.5397
