COMMON SOURCE Meaning and
Definition
-
Common source refers to a fundamental concept in various disciplines, including physics, electronics, and social sciences. In physics and electronics, a common source is a configuration or arrangement where a component or system provides a shared or common output or influence. This term is often used in circuits involving amplification, where a common source amplifier relies on a transistor or other devices to amplify an input signal and produce an amplified output signal.
In the field of electronics, a common source is an amplifying stage configuration, functioning as an inverting amplifier. It consists of a single transistor with its source terminal connected to the ground potential. The input signal is applied to the gate terminal, and the amplified output signal is obtained from the drain terminal. This configuration is commonly used in analog circuits, such as audio amplifiers, where the signal is grounded and transformed into a higher-power form.
In the context of social sciences, a common source refers to an origin or cause that is shared by multiple phenomena or entities. It can be a common factor or influence that affects multiple variables, outcomes, or effects observed in a system or group. This concept is often used to explain the similarities or patterns observed in various social phenomena, such as cultural practices, language development, or economic indicators. By identifying a common source, researchers can better understand the underlying mechanisms and relationships between different aspects of a social system or group.
Etymology of COMMON SOURCE
The etymology of the term "common source" is derived from the combination of the words "common" and "source".
The word "common" originates from the Latin word "communis", meaning "belonging to or shared by all". It evolved through Old French and Middle English before taking its current form.
The term "source" stems from the Latin word "sors", meaning "fountain or spring". It passed through Old French as "sorse" before becoming "source" in Middle English.
When combined, "common source" refers to something that is shared or originates from a central or shared origin. In different contexts, it may refer to a shared origin of information, a common ancestor or lineage, or a collective point of origin for various elements.
