A good voltage regulation of a transformer means that the output voltage fluctuation from no load to full load is least. Therefore, the correct answer is A.
Voltage regulation refers to the ability of a transformer to maintain a relatively stable output voltage under varying load conditions. Ideally, a transformer should be able to provide a constant output voltage regardless of the load connected to it.
In practice, however, transformers have inherent losses and impedance that can cause the output voltage to deviate from the desired value. The voltage regulation of a transformer is a measure of this deviation and is typically expressed as a percentage.
A low voltage regulation indicates that the transformer can maintain the output voltage close to the desired value, even when the load changes from no load (minimum load) to full load (maximum load). This is desirable as it ensures a stable and consistent supply of electricity to the connected load.
Option A correctly states that a good voltage regulation means that the output voltage fluctuation from no load to full load is least, making it the correct answer.

A good voltage regulation of a transformer meansa)output voltage fluct...

Explanation:

Output Voltage Fluctuation:
- A good voltage regulation of a transformer means that the output voltage fluctuation from no load to full load is least.
- This ensures that the voltage remains stable and within the desired range regardless of the load variations.

Primary and Secondary Voltage Difference:
- The primary and secondary voltage difference being least or maximum does not directly relate to voltage regulation.
- Voltage regulation is more focused on maintaining a stable output voltage under varying load conditions.

Conclusion:
- Therefore, the correct answer is option 'A' as it directly addresses the key aspect of voltage regulation in a transformer, which is minimizing output voltage fluctuation from no load to full load.
