![]() When we connect a wire from anode to cathode through the bulb, the electrons try to go to cathode side through bulb. But there is a material called electrolyte which stops those electrons so they try in another way. In battery, the only place with less number of electrons is cathode. These electrons try to go to the place where there is less number of electrons are present. Due to these reactions, some electrons will be produced and they will make grab at the position of anode. If you observe the figure, some reaction will occur between chemicals used in it which is called as electro-chemical reaction. Generally batteries contains three parts. Here I’m discussing about how the batteries work. A battery is a device consisting of one or more electro-chemical cells that convert stored chemical energy into electrical energy.
