batterispænding

Batterispænding, often referred to as voltage, is a fundamental electrical property of a battery. It represents the potential energy difference between the positive and negative terminals of the battery. This difference in electrical potential is what drives electric current to flow when a circuit is connected.

The unit of measurement for batterispænding is the volt (V). Different types of batteries have different nominal voltages. For example, a standard AA alkaline battery typically has a voltage of 1.5 volts, while a car battery might have a voltage of 12 volts. Lithium-ion batteries, common in portable electronics, can have voltages ranging from 3.7 volts to higher values depending on their configuration.

Batterispænding is crucial for determining the compatibility of a battery with an electronic device. Devices are designed to operate within a specific voltage range, and using a battery with a voltage outside this range can either prevent the device from functioning or, in some cases, damage it. As a battery discharges, its voltage gradually decreases. This voltage drop is an indicator of the remaining charge within the battery.
