A student writes:
'A battery is a store of charge. When a lamp is connected to the battery, the charge flows out of the battery and is used up in the lamp. When all of the charge has been used up, the battery is flat.'
Explain why the student's ideas are wrong.
Your answer should refer to charge, current, energy and potential difference.
