उत्तर

  1. Copper and aluminium are excellent electrical conductors.
  2. Since the resistance of copper and aluminium is very low, the amount of heat generated while carrying an electric current through them is also low.

Therefore, copper or aluminium wires are used for electricity transfer.

Tara, after completing her exams, went to her grandmother's house along with her younger brother Rahul. One day, Rahul came home after playing and switched on the fan and air conditioner. At the same time, his grandmother was preparing a milkshake for him using a mixer. Suddenly, they heard a big sound and the electricity of the house got shut down. Tara is called an electrician. He said the main reason for supply to shut down was overloading.
