प्रश्न

Give a scientific reason.

For electric power transmission, copper or aluminium wire is used.

कारण सांगा

उत्तर

  1. Copper and aluminium are excellent electrical conductors. Since the resistance of copper and aluminium is very low, the amount of heat generated while carrying electric current through them is also low.
  2. Therefore, copper or aluminium wires are used for electricity transfer.

In a set up the students coated iron nails with zinc metal and noted that, iron nails coated with zinc prevents rusting. They also observed that zinc initially acts as a physical barrier, but an extra advantage of using zinc is that it continues to prevent rusting even if the layer of zinc is damaged. Name this process of rust prevention and give any two other methods to prevent rusting.
