| List I | List II | ||
| (a) | Rectifier | (i) | Used either for stepping up or stepping down the AC voltage. |
| (b) | Stabilizer | (ii) | Used to convert AC voltage into DC 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 changes. |
Choose the correct option from the given ones:
| 1. | (a)–(ii), (b)–(iv), (c)–(i), (d)–(iii) |
