AC Generator & Transformer
Match List I with List II.
Choose the correct answer from the options given below:
| List I | List II | ||
| (a) | Rectifier | (i) | Used either for stepping up or stepping down the a.c. voltage |
| (b) | Stabilizer | (ii) | Used to convert a.c. voltage into d.c. voltage |
| (c) | Transformer | (iii) | Used to remove any ripple in the rectified output voltage |
| (d) | Filter | (iv) | Used for constant output voltage even when the input voltage or load current change |
Show answer and solution
Answer: (a)
- Rectifier converts AC to DC: (a)-(ii).
- Stabilizer gives constant output voltage despite input or load changes: (b)-(iv).
- Transformer steps AC voltage up or down: (c)-(i).
- Filter removes ripple from rectified output: (d)-(iii).
- So the answer is (a).
