Question:

Based on the understanding operations of rectifies answer the questions Diodes can be used for rectifying on ac voltage (restricting the ac voltage to one direction) with the help of a capacitor or a suitable filter, a dc voltage ca be obtained.

Arrange the device in the process of conversion of alternating current to direct current in proper sequence.

(A) Filter

(B) Rectifier

(C) Amplifier

(D) Transformer

Choose the correct answer from the options given below :

Options:

A, C, B, D

D, B, A, C

D, C, B, A

D, A, B, C

Correct Answer:

D, B, A, C

Explanation:

The correct answer is option (2) : D, B, A, C

  1. Transformer (D) → adjusts AC voltage level
  2. Rectifier (B) → converts AC to pulsating DC
  3. Filter (A) → smoothens the pulsating DC
  4. Amplifier (C) → increases the strength of the DC signal (if required)

So, the correct order of conversion is: Transformer → Rectifier → Filter → Amplifier
