प्रश्न

The secondary windings of a transformer in which the voltage is stepped down are usually made of thicker wire than the primary. Explain why.

उत्तर

The secondary windings of a transformer in which the voltage is stepped down are usually made up of thicker than the primary because more current flows in the secondary coil. The use of thicker wire reduces its resistance and therefore the loss of energy as heat in the coil.
