In the theory of electrical networks, a dependent source is a voltage source or a current source whose value depends on a voltage or current elsewhere in the network. [ 1 ] Dependent sources are useful, for example, in modeling the behavior of amplifiers.
A schematic diagram of a voltage source, V, driving a resistor, R, and creating a current I. A voltage source is a two-terminal device which can maintain a fixed voltage. [1] An ideal voltage source can maintain the fixed voltage independent of the load resistance or the output current. However, a real-world voltage source cannot supply ...
When a dependent source is contained within an essential mesh, the dependent source should be treated like an independent source. After the mesh equation is formed, a dependent source equation is needed. This equation is generally called a constraint equation. This is an equation that relates the dependent source’s variable to the voltage or ...
As another example, two scientific devices could be considered independent sources of measurement data, unless they shared the same wiring or electrical power supply (or similar factors). Consulting multiple independent sources is a common technique for detecting errors and deception , as any divergences or contradictions between statements, or ...
A simple electric circuit made up of a voltage source and a resistor. Here, =, according to Ohm's law. An electrical network is an interconnection of electrical components (e.g., batteries, resistors, inductors, capacitors, switches, transistors) or a model of such an interconnection, consisting of electrical elements (e.g., voltage sources, current sources, resistances, inductances ...
Material available from sources that are self-published, primary sources, or biased because of a conflict of interest can play a role in writing an article, but it must be possible to source the information that establishes the subject's real-world notability to independent, third-party sources. Reliance on independent sources ensures that an ...
If the dependent variable is referred to as an "explained variable" then the term "predictor variable" is preferred by some authors for the independent variable. [22] An example is provided by the analysis of trend in sea level by Woodworth (1987). Here the dependent variable (and variable of most interest) was the annual mean sea level at a ...
