Detailed Solution
Download Solution PDFThe correct answer is option 2):(Primary winding will burn out)
Concept:
- When DC supply is given to the primary of the transformer, The alternating flux cannot be generated
- The primary will have lower resistance
- The winding acts as a short circuit across the terminals of the Direct current t(DC) source that leads to the flow of heavy current through the winding resulting in overheating of the winding.
- Primary winding will burn out when the rated DC supply is given to the primary of the transformer
- The transformer works on the principle of mutual induction. so it only operates on alternating current
