Question

Arrange the following components in the order of their function in power supply

(A) Voltage regulator
(B) Rectifier
(C) Transformer
(D) Filter
Choose the correct answer from the options given below:

• A. (B), (A), (C), (D).
• B. (A), (B), (C), (D).
• C. (B), (A), (D), (C).
• D. (C), (B), (D), (A).

Hint:

In a power supply, the sequence is: Transformer → Rectifier → Filter → Voltage Regulator.

Answer 1

The Correct Option is D

Step 1: Understand the sequence of operations in a power supply.
1. Transformer (C): First step in converting AC voltage, stepping it up or down.
2. Rectifier (B): Converts AC to DC by using diodes to rectify the AC signal.
3. Filter (D): Smoothens the rectified DC voltage by reducing fluctuations.
4. Voltage regulator (A): Maintains a constant DC voltage, even if the input voltage varies.
Step 2: Conclusion.
The correct order of operation is: \[ \text{Transformer} \rightarrow \text{Rectifier} \rightarrow \text{Filter} \rightarrow \text{Voltage Regulator} \]
Final Answer: \[ \boxed{\text{(C), (B), (D), (A)}} \]
