In a transformer the tappings are generally provided on

Solution (By Examveda Team)

In a transformer, tappings are usually provided on the low voltage side of the transformer. This is because the low voltage side is more flexible and easier to adjust, allowing for more precise control of voltage variations. These tappings help in controlling the output voltage in certain applications where the exact output voltage is needed for specific devices or systems.

Tapping on the low voltage side is common in transformers because it provides easy access to change or regulate the voltage as needed. In most transformers, the low voltage side is where adjustments are made to either step up or step down the voltage.

On the other hand, the primary side and secondary side are usually involved in the primary voltage transfer and do not typically have adjustable tappings. The high voltage side also doesn't need tappings as adjustments are not typically required here in normal operation.

Thus, the correct answer is Option C: low voltage side, as the low voltage side is where tapping is commonly provided in transformers.
