Amperóra

Amperóra, also known as ampere-hour or amp-hour, is a unit of electrical charge. It is commonly used to measure the capacity of rechargeable batteries, such as those used in portable electronic devices. One ampere-hour is equal to the amount of electric charge passed when a current of one ampere flows for one hour.

The capacity of a battery is typically expressed in ampere-hours, with higher values indicating a greater capacity. For example, a 2000 mAh (milliampere-hour) battery can deliver 2000 milliamperes of current for one hour, or 2000 milliamperes for 30 minutes, or 1000 milliamperes for two hours, and so on.

Amperóra is an important consideration when selecting batteries for electronic devices. A higher capacity battery will provide longer runtime between charges, but may also be heavier and more expensive. Conversely, a lower capacity battery may be lighter and less expensive, but will require more frequent charging.

In addition to battery capacity, amperóra is also used to measure the amount of electric charge passed in an electrical circuit. This is often done using an ammeter, which is an instrument that measures the current flowing through a circuit.

Overall, amperóra is a fundamental unit in the field of electronics, playing a crucial role in the design and operation of battery-powered devices.
