प्रश्न
Below is the diagram of a transformer:
- Identify the type of transformer.
- In this type of transformer which of the wire is thicker, the primary or the secondary? Give a reason.
उत्तर
- Step-down transformer.
- Due to the step-down transformer's decreased voltage, the secondary coil's wire is thicker than the primary coil's. Hence, the secondary coil's current is greater than the primary coil's. Thus, the secondary coil needs thick wires.
