Cells generate electricity through chemical reactions. There are several common types of cells: dry cells, mercury cells, nickel cadmium cells, and lithium ion cells. Dry cells consist of a zinc container holding a mixture of manganese dioxide and carbon powder with an electrolyte and graphite rod. Chemical reactions in the cell produce electricity that flows through connected devices. Mercury cells are similar but smaller in size and contain mercury, making them an environmental hazard. Storage cells like nickel cadmium and lithium ion cells can be recharged for reuse unlike dry and mercury cells.

This document discusses voltaic cells and electrochemistry. It describes how a simple voltaic cell works using two different metals, like zinc and copper, immersed in an electrolyte solution. Electrons flow from the more reactive metal (zinc) to the less reactive metal (copper). The zinc acts as the anode and corrodes as it loses electrons, while the copper acts as the cathode. A Daniel cell is given as an example using zinc and copper electrodes separated by a salt bridge in their respective solutions. The salt bridge allows ion flow between the solutions while preventing mixing. At the anode, zinc atoms lose electrons and form ions, while at the cathode, copper ions gain electrons and form copper metalP.p.t on types of electric cells

- 2. CHANGES ( ENCASED ELECTRICITY)
- 3. CELLS Cells are systems which generate electricity through chemical changes. The common types of cells are Dry Cell Mercury Cell Nickel Cadmium Cell Lithium Ion Cell
- 4. DRY CELL
- 5. Components of a Dry Cell The dry cell consists of a zinc container having a mixture of manganese dioxide and carbon powder into which a graphite rod is inserted. In between the mixture and the rod, there is a paste of ammonium chloride and zinc chloride which act as the electrolyte.
- 7. Equipments using Dry Cell
- 8. Working of a Dry Cell When the zinc container and the brass cap of the graphite rod are connected to a device, using wires, electricity produced by the chemical reaction in the cell will flow through the device.
- 9. MERCURY CELL( BUTTON CELL)
- 10. Components of a Mercury Cell The mercury cell is made by filling chemicals like mercury, mercuric oxide, carbon powder, zinc oxide etc in a steel container having the size of a button. Mercury cells are used in watches, calculators, small torches and toys. Because of the presence of the highly poisonous mercury, throwing them away after use is becoming an environmental hazard.
- 12. Equipments using Mercury Cell
- 13. Storage Cells Dry cells and Mercury cells are not rechargeable. Cells which can be recharged and reused are called stoage cells. Common examples of storage cells include Nickel Cadmium Cell Lithium Ion Cell
