Q5. Transformers Dc supply pe work kyu nhi karta hai?
Ans. 
Transformers cannot operate on DC supply due to the absence of changing magnetic fields required for induction.
• Transformers rely on electromagnetic induction, which requires a changing magnetic field.

• DC supply provides a constant voltage, resulting in a steady magnetic field that does not induce current.

• When DC is applied, the transformer core can saturate, leading to overheating and potential damage.

• Example: A transfo...read more
