Me chota sa, when I was around 5 years old I use to lie next to my father for a little while before going to my own bed and use to ask him questions, it was the time when we didn't have an AC in our apt in Rahim Yar Khan thus we use to sleep in the courtyard at summer nights, once I asked him a question which he really appreciated, the question was: when electricity goes in a fan, the fan starts revolving whereas when the light goes in a bulb, it lights up, how same electricity perform these 2 entirely different kind of functionalities? He explained to me how the light bulb and motor of a fan works.
