feszültségtartományokat

Feszültségtart is a Hungarian term that translates to "voltage retention" or "voltage holding" in English. It refers to the ability of an electrical component or system to maintain a certain voltage level over a period of time, even when not actively supplied with power or when subjected to certain conditions. This phenomenon is particularly relevant in the context of capacitors, batteries, and certain types of semiconductor devices.

In capacitors, voltage retention relates to their self-discharge rate. A capacitor with good voltage retention will lose its stored charge more slowly, meaning the voltage across its terminals will decrease at a lower rate when disconnected from a power source. This is important for applications where a capacitor needs to hold a charge for an extended period, such as in backup power supplies or timing circuits.

For batteries, voltage retention can describe how well a battery maintains its terminal voltage under load and during periods of inactivity. A battery with good voltage retention will exhibit less voltage sag under load and will retain a higher percentage of its open-circuit voltage after a period of storage. This is a key factor in assessing battery performance and longevity.

In some electronic circuits, voltage retention might also refer to the residual voltage present in a circuit after power has been removed, which can be a safety consideration or a factor in circuit design to prevent unintended operations. The specific meaning and importance of feszültségtart are context-dependent, but it generally signifies the stability and longevity of a voltage level within an electrical system.
