Cells in a series

• As already discussed cells give a voltage of around 1.5 V -2V
• A lot of appliances required a higher voltage to function
• Several cells can be joined together to giver larger voltages
• This can be achieved by joining the cells in series
• When this is done the voltages of the individual cells is added up together
• Resulting in a higher voltage
• As the potential difference used to move electrons around the circuit is increased
• The result is a battery
• Battery-is when cells are joined together in series to give a higher voltage
• For example most cars have at least one 12 V battery
• This is made up of joining six 2 V cells together
• Torches may have three 1.5 V cells resulting in a 4.5V battery
• In series- the negative terminal of one cell is connected to the positive terminal of the next cell
