cells and batteries

• what is the voltage produced by a cell dependent on


  electrode and electrolyte
• simple cell

  made by connecting two different materials with electrolyte
• batteries


  consist of two or more cells connected together in series to provide a greater voltage
• non rechargeable cells and batteries


  chemical reactions stop when one of the reactions have been used up
• alkaline batteries


  non rechargeable
• rechargeable cells and batteries


  can be recharged because the chemical reactions are reversed when an external electric current is supplied
