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

Transformer is an electrical device which is used to transfer electrical energy from one circuit to another through mutual induction. In order to ensure that the transformer is functioning properly, voltage regulation is necessary.

What is voltage regulation?

Voltage regulation is defined as the change in output voltage from no load to full load expressed as a percentage of the rated voltage. It is an important parameter to ensure that the transformer is functioning within its specified limits.

What is a good voltage regulation?

A good voltage regulation of a transformer means that the output voltage fluctuation from no load to full load is least. This is because the output voltage of a transformer should remain constant regardless of the load connected to it.

Why is output voltage fluctuation undesirable?

Output voltage fluctuation can cause problems in electrical equipment that is connected to the transformer. If the voltage is too low, the equipment may not function properly, and if the voltage is too high, the equipment may get damaged. Therefore, a good voltage regulation is necessary to ensure that the equipment is protected from voltage fluctuations.

Conclusion:

In conclusion, 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 transformer is functioning properly and that the electrical equipment connected to it is protected from voltage fluctuations.
