tehojännitteestä

Tehojännite, also known as operating voltage or working voltage, refers to the electrical potential difference at which a device or system is designed to function. It is the voltage that is applied to the terminals of a component or circuit to enable its intended operation. This value is critical for ensuring proper performance and avoiding damage. For example, a light bulb has a specific tehojännite that, when applied, causes it to emit light at its rated brightness. Similarly, electronic components like resistors, capacitors, and semiconductors have maximum tehojännite ratings that should not be exceeded.

Operating outside the specified tehojännite can lead to various consequences. If the applied voltage is too low, the device may not function at all, or it may operate inefficiently. If the voltage is too high, it can cause excessive current flow, leading to overheating, permanent damage, or even catastrophic failure. Therefore, understanding and adhering to the tehojännite is a fundamental aspect of electrical engineering and electronics. This value is typically specified by the manufacturer on the device's datasheet or label.
