What is meant by a linear dependent source?

What is meant by a linear dependent source?

A linear dependent source is a voltage or current source that depends linearly on some other circuit current or voltage. Example: You watch a certain voltmeter V1 and manually adjust a voltage source Vs to be 2 times this value. This constitutes a voltage-dependent voltage source.

What are dependent sources examples?

Dependent sources are useful, for example, in modelling the behavior of amplifiers. A bipolar junction transistor can be modelled as a dependent current source whose magnitude depends on the magnitude of the current fed into its controlling base terminal.

How many types of dependent source are there?

4 types
Explanation: Dependent sources are 4 types. Voltage controlled voltage/current source and current controlled current/voltage source. Explanation: The name dependent itself tells us that they are dependent on some other source.

What is Vccs and Ccvs explain in detail?

Four types of controlled sources are available: current controlled current source (CCCS), voltage controlled current source (VCCS), current controlled voltage source (CCVS), and voltage controlled voltage source (VCVS). Controlled sources can be controlled by any voltage or current from the model.

Which of the following is not an example of linear element?

Examples of non-linear elements are VDR, thermistor and LDR.

What is meant by linear and nonlinear elements?

Circuits with only linear elements, linear circuits, do not cause intermodulation distortion, and can be easily analysed with powerful mathematical techniques such as the Laplace transform. Nonlinear elements – these are elements in which the relation between voltage and current is a nonlinear function.

Where are dependent sources used?

Ideal dependent sources are commonly used in the analysing the input/output characteristics or the gain of circuit elements such as operational amplifiers, transistors and integrated circuits.

What is the difference between dependent and independent sources?

Independent Source: It is an active element that provides a specified voltage or current that is completely independent of other circuit variables. Dependent Source: It is an active element in which the source quantity is controlled by another voltage or current in the circuit.

What are independent voltage sources?

An independent voltage/current source is an idealized circuit component that fixes the voltage or current in a branch, respectively, to a specified value. Remember that the state of a circuit is given by the voltage across and current through each branch of the circuit.

What is voltage dependent current source?

A dependent source is a current or voltage source whose value is not fixed (i.e., independent) but rather which depends on some other circuit current or voltage. The general form for the value of a dependent source is Y=kX where X and Y are currents and/or voltages and k is the proportionality factor.

What is voltage controlled voltage source?

Voltage-controlled voltage source (VCVS)Edit This is a voltage source whose value is controlled by another voltage elsewhere in the circuit. Its output will typically be given as. , where A is a gain term and Vcis a control voltage.
