Hi ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Two stupid people were having a discussion, by the way one was me, that whether the cell phone charger consumes power or not when it is not connected to the phone (assuming it is connected to the mains). I was of the opinion that it does consume power. It outputs DC current which can be thought of as a continuous push of electrons. Think of someone pushing a wall. Although, in physics terms, no work is being done, 'biological' energy is still being invested. Likewise, electrons at the tip of charger's pin which goes into the cell phone are continuously pushed but they can't flow outward. It's just like a water pump which is continuously pumping water but the pumped water is not used for any useful activity. I have noticed that charger, connected to the mains, gets hot even when no cell phone is connected. Please let me know if I'm correct. Thank you.
