ZIMSEC O Level Combined Science Notes: 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
