Answer:
Explanation:
invented electric battery. It was first named as Voltaic Pile. For his contributions to science, the unit of electric potential is named as Volt. John Frederic Daniell developed Daniell cell. Then George Leclanche invented Wet cell and Dr. Carl Gassner introduced the Dry cell battery. Gaston Plante introduced the first rechargeable battery. It is the lead-acid battery and is again most common application found in cars.
Cell
We know that electrical current is the flow of charged particles. It is the flow of electrons through a circuit.
A collection of two or more cells which are connected in series is called A Battery. A battery is an energy source that converts chemical energy to electrical energy. It is otherwise known as Electrochemical Cell. The energy is stored in the form of chemical energy inside a battery. Batteries give us a convenient source of energy for energizing devices without cables and wires. When it is connected to a circuit it produces electrical energy. A battery consists of two terminals – A Positive and Negative Terminal. The positive terminal is called Cathode and the negative terminal is called Anode. They are also called as Electrodes of a Cell. These electrodes will be dipped in a solution called Electrolyte. It is liquid which is ionic and conducts electricity.
When the battery is about to charge, an external source is connected to it. The anode of the battery is connected to the negative terminal of the source and cathode is connected to the positive terminal of the source. As the external source is connected to the battery, electrons are inserted into the anode. When the cell or battery is connected to the circuit chemical reactions takes place. Thus chemical reactions takes place within the two electrodes. Here oxidation and reduction reactions happens. Then reduction reaction occurs at cathode and oxidation process occurs at anode.
