Fan And Me

As a doctor, my younger brother has more to show his importance to my family members and neighbors. But being an engineer, I don't get much chance to showcase my abilities with practical utilities to people, other than engineers or scientists. Then, there is this opportunity I somehow convinced my mother of the importance of being an electrical engineer. It happened as the speed of ceiling fan of my room was not as fast as it should normally be. When the electrician came, he just replaced condenser of fan. Surprisingly, even though the fan was speeding fast, it was not throwing air downwards. Actually, all the air was being thrown upwards as the speed of fan had got reversed. Electrician had no idea how it happened.  And that was the time, I remembered the question asked during comprehensive viva about single phase induction motor during my engineering days in IIT, BHU and it took no time to realize that, in fact, the winding of condenser had been interchanged and therefore, the torque had got reversed. I just convinced the electrician to change the condenser location  and with all the surprise of my mother and electrician, the fan started running in the usual direction. And that was the time, my mother proudly introduced me as scientist to the electrician and It made my day. :)
