or:The Leclanch\u00e9 cell is a battery invented and patented by the French scientist Georges Leclanch\u00e9 in 1866. The battery contained a conducting solution (electrolyte) of ammonium chloride, a cathode (positive terminal) of carbon, a depolarizer of manganese dioxide, and an anode (negative terminal) of zinc.en.wikipedia.org/wiki/Leclanch\u00e9_cellb) \"electric cell\" does not identify any particular device.c) \"dynamo\" is a magnetic generator using a mechanical rectifier to produce DC power. It was formerly the only kind of generator used in cars to charge the battery.d) \"solar cell\" is ... solar.Energy is not a physical unit. It is a philosophical concept and an accounting technique used to analyze mechanical and chemical exchanges. In nuclear physics it is defined as a wavelength of light, in biology it is a synonym for metabolism, and in public utilities they say energy when they mean connectivity. Anybody who uses the word in any other context either does not know what he is talking about, or is peddling something you don't need.
