Meaning and Usage

The term "open-circuit impedance parameter" refers to a specific electrical parameter used in the analysis of circuits, particularly in the context of two-port networks. Open-circuit impedance describes how much impedance is present when there is no load connected to a circuit.

In electrical engineering, this parameter is crucial for determining how a circuit will behave under certain conditions, especially with regard to signal transmission and reflection. The term is frequently used in technical and academic contexts, particularly in written form such as research papers, textbooks, and technical documentation, rather than in everyday conversation.

Frequency of Use

This term is specialized and primarily used in electrical engineering, physics, and related fields. It tends to appear more often in written contexts, such as scientific literature and technical reports, rather than in casual speech.

Example Sentences

1. The open-circuit impedance parameter was crucial for our analysis of the system's stability.

2. Translation: Параметр импеданса открытого контура был решающим для нашего анализа стабильности системы.

3. Engineers must pay close attention to the open-circuit impedance parameter when designing RF circuits.

Etymology

The term "open-circuit" derives from the concept of an electrical circuit that is not complete, allowing for no current flow. "Impedance" comes from the Latin stem impedere, meaning "to hinder" or "to obstruct." The word "parameter" is derived from the Greek roots para- (beside) and metron (measure), indicating a measure that defines characteristics of a function or system.
