How are multiple cells connected to create a battery?

Multiple cells are connected together to form a battery, usually by connecting them in series.

In a series connection:

• The positive terminal of one cell is connected to the negative terminal of the next cell
• This arrangement adds up the voltages of individual cells, resulting in a higher overall potential difference

This is done when more voltage is required to operate a device.

Cells can also be connected in parallel, where:

• All positive terminals are connected together, and all negative terminals are connected together
• This increases the current capacity and battery life rather than voltage

Thus, the method of connection depends on whether higher voltage or longer duration of current supply is needed.
