Is it possible to eliminate dependent sources on superposition

This is not a limitation though because power can be computed from the resulting voltage or current values. Power calculation cannot be done by superposition principle because power is not linear function of voltage or current. Superposition is not applicable if any redundant source will present in the circuit. Superposition is not applicable if any non-linear component is present in circuit. The superposition theorem states that a circuit with multiple voltage and current sources is equal to the sum of simplified circuits using just one of the sources.

A built-in electric field is Q: A 4 pole , long shunt compound generator supplies A at a terminal voltage of volts. If the ar If you want any How many responses are obtained from an N number of independent sources present in a given circuit?

For N number of independent sources, there are also equivalent N numbers of responses. According to superposition theorem, each independent source produces its own individual response over the circuit. The algebraic sum of the individual responses is equal overall or linear response.

Is it possible to eliminate dependent sources on superposition? Dependent sources cannot be eliminated in superposition theorem. That is because, at different value of independent source, different parameters e.

By the application of the theorem, only independent sources must be eliminated, retaining the dependent sources. What are the possible limitations of the superposition theorem?

The basis of superposition theorem is the linearity principle. Thus, one limitation of the theorem is when the circuit is nonlinear.

Meaning, dependent sources are present, where its magnitude depends on one of the independent sources. Why is it "prohibited" to treat dependent sources this way when the results are the same? The author has investigated the presentation of superposition in circuits texts by surveying twenty introductory books on circuit analysis. Fourteen explicitly state that if a dependent source is present, it is never deactivated and must remain active unaltered during the superposition process.

The remaining six specifically refer to the sources as being independent in stating the principle of superposition. Three of these present an example circuit containing a dependent source which is never deactivated. The other three do not present an example in which dependent sources are present. From this limited survey, it is clear that circuits texts either state or imply that superposition of dependent sources is not allowed.

The author contends that this is a misconception. Do not attempt to solve for a numeric answer until the superposition sum has been written.

The solution lies to the answer of the question, " why we want superposition theorem". Now if you want to turn off the dependent source turn it off, no problem, and if you find it easy to leave it on, then that is also fine, since , the linearity is followed by the elements and voltage and current function.

You can actually find networks where you can treat dependent sources as independent, imagine a net where a dependent source is a controlled voltage source with only one terminal connected, it's clear that it will not affect the circuit in any way so you can treat it pretty much how you want. All in all the fact that such examples exist does not mean that such a method is general. Sign up to join this community. The best answers are voted up and rise to the top.
