Batteries

Test yourself on Batteries

• A battery that has a voltage output of 9V is made up of 3 identical cells. What is the voltage output of each of its individual cell components?

• A 5V cell and a 3V cell are connected in series (joined end-to-end). What is the output voltage of the battery?

• How are cells connected together in batteries?

• What happens to a battery once the chemicals inside it run out?
