प्रश्न
Bends in a rubber pipe reduce the flow of water through it. How would the bands in a wire affect its electric resistance?
Advertisements
उत्तर
Bends in the wire will not affect its resistance. This is because the electrons are extremely small in size as compared to the bends. So, the electrons can easily change their direction of motion.
