Jännitteensiirto, known in English as voltage transfer, is a fundamental concept in electronics and electrical engineering. It describes the process by which an electrical voltage is conveyed from one point in a circuit to another, or from one circuit to a different one. This transfer is essential for the operation of virtually all electronic devices and power systems.

The method of voltage transfer depends heavily on the context. In direct current (DC) circuits, voltage is simply present across conductive paths. For alternating current (AC) circuits, voltage transfer is often achieved through the use of transformers. These devices utilize electromagnetic induction to step voltage up or down, facilitating efficient transmission over long distances or adapting voltage levels for specific applications.

In more complex electronic circuits, transistors and operational amplifiers are frequently employed to transfer and manipulate voltage signals. These components can amplify or attenuate voltage, switch it between different paths, or perform logical operations based on voltage levels. The fidelity of voltage transfer is a critical parameter, as any distortion or loss can significantly impact circuit performance. Understanding the principles of jännitteensiirto is therefore crucial for designing, analyzing, and troubleshooting electrical and electronic systems.
