Q1. Why we cannot operate transformer in dc supply
Ans. 
Transformers cannot operate on DC supply due to the absence of changing magnetic field required for induction.
• Transformers work on the principle of electromagnetic induction, which requires a changing magnetic field.

• DC supply produces a constant magnetic field, which does not induce a voltage in the secondary coil of the transformer.

• AC supply, on the other hand, produces a changing magnetic field, allowing for inductio...read more

Q1. Why we cannot measured transformer in kw
Ans. 
Transformers cannot be measured in kW because they do not consume power, they only transfer it.
• Transformers do not have any moving parts or internal power losses, so they do not consume power themselves

• The power rating of a transformer is given in kVA (kilovolt-amperes) which represents the maximum amount of power it can transfer

• The power factor of the load connected to the transformer determines the actual power in kW
