Terhelésfeszültség

Terhelésfeszültség is a Hungarian term that translates to "load voltage" or "voltage under load" in English. It refers to the voltage present across an electrical component or circuit when it is actively drawing current and performing its intended function. This is distinct from the open-circuit voltage or no-load voltage, which is the voltage measured when no current is flowing.

The magnitude of the terhelésfeszültség is typically lower than the no-load voltage. This reduction is due to various factors, including the internal resistance of the source (such as a battery or power supply) and the resistance of the connecting wires and the load itself. As current flows through these resistances, a voltage drop occurs according to Ohm's law (V = I * R). Consequently, the voltage available at the terminals of the load is diminished.

Understanding terhelésfeszültség is crucial in electrical engineering and electronics design. It affects the performance of devices, as many components are designed to operate within a specific voltage range. For example, a motor's speed and torque will depend on the terhelésfeszültség it receives. Similarly, the brightness of a light bulb or the charging rate of a battery is influenced by this parameter. Accurate measurement and consideration of terhelésfeszültség are essential for ensuring the proper and efficient functioning of electrical systems.
