Ampere-hour

An ampere-hour is a way to measure how much electricity a battery or device can hold or use. An ampere is a unit that measures electricity flowing through something, and an hour is a unit of time. So, an ampere-hour measures the amount of electricity that can flow through something for an hour. It's like if you have a cup and you want to measure how much water it can hold, an ampere-hour is like measuring how much electricity the cup can hold or use.
