Match List I with List II. List I (a) Rectifier (b) Stabilizer (c) Transformer (d) Filter List II (i) Used either for stepping up or stepping down the a.c. voltage (ii) Used to convert a.c. voltage into d.c. voltage (iii) Used to remove any ripple in the rectified output voltage (iv) Used for constant output voltage even when the input voltage or load current change Choose the correct answer from the options given below:

1. (a) – (ii), (b) – (iv), (c) – (i), (d) – (iii)
2. (a) – (iii), (b) – (iv), (c) – (i), (d) – (ii)
3. (a) – (ii), (b) – (i), (c) – (iv), (d) – (iii)
4. (a) – (ii), (b) – (i), (c) – (iii), (d) – (iv)

Correct answer: (a) – (ii), (b) – (i), (c) – (iii), (d) – (iv)

Solution

The correct option accurately matches each device with its primary function: a rectifier converts AC to DC, a transformer adjusts voltage levels, a filter smooths out the output from the rectifier, and a stabilizer maintains a constant output voltage despite variations in input or load.
