प्रश्न
Name the coil of which the wire is thicker in a step down transformer. Give reason to your answer.
उत्तर
In a step-down transformer, the wire in the secondary coil is thicker than in the primary coil. The reverse is the case of a step-down transformer. Thus, the thickness of the wire is chosen accordingly.
