Question:
The order of (a) transformer (b) diode rectifier (c) filter (d) voltage regulator in a block diagram of simple rectifier circuit is as
(a) b, d, c, a
(b) a, c, d, b
(c) a, b, c, d
(d) d, c, a, b
The order of (a) transformer (b) diode rectifier (c) filter (d) voltage regulator in a block diagram of simple rectifier circuit is as
(a) b, d, c, a
(b) a, c, d, b
(c) a, b, c, d
(d) d, c, a, b
Show Hint
A power supply first steps the AC voltage down, then rectifies, smooths and finally regulates it.

Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
A simple DC power supply has four stages in this order.
Step 2: Stages
Transformer (a) changes the AC voltage level.\nDiode rectifier (b) converts AC to pulsating DC.\nFilter (c) smooths the ripple.\nVoltage regulator (d) keeps the output steady.
Step 3: Order
The order is a, b, c, d, which is statement (c) in the question.
Final Answer:
The correct order is transformer, rectifier, filter, regulator, that is a, b, c, d. \[ \boxed{\text{(C) }\text{c}} \]
