One day Sohan went to his friend's house. He was surprised to see that most of the electrical appliances at his house were functional. For example, tube light and fan in all rooms two TV's, computer, light of toilet & kitchen were switched on. Sohan told his friend that this is not the way to use electricity. Now the question arises whether this habit of consuming electrical energy is acceptable or not. Will it effect the economic condition of the family, as well as the nation how?
