Thevenin's Theorem is especially useful in analyzing power systems and other circuits where one particular resistor in the circuit (called the "load" resistor) is subject to change, and re-calculation of the circuit is necessary with each trial value of load resistance, to determine voltage across it and current through it.

∙ 11y agoanytime you want to analyze a circuit with multiple resistances and/or reactances and it would be easier to analyze as an equivalent circuit with fewer resistances and/or reactances. thevenization tells you how.

∙ 14y agoA Thevanin equivalent is the analytic substitution of an arbitrary circuit containing voltage sources, current sources, and resistors, presenting just two connections to the point of analysis, which a single voltage source in series with a single resistor. It is used during circuit analysis as a simplification tool.

Conclusion about thevenin's theorem?
Thevenin's theorem is a basic equivalence principle for circuit design. It can simplify a very complex circuit to a very simple equivalent. This is done by finding the Thevenin Resistance as well as the Thevenin voltage and current. Once these are known, the equivalent circuit is simply a voltage source in series with a resistance.
Is thevenin's theorem is applicable for dc and ac both?
no only ac, im a science and math professsor
Is thevenin's theorem applicable in transient analysis or it should be used only for steadystate analysis?
Yes it is applicable in both. With transient analysis, it is standard to use thevenin or norton equivalents to minimize the circuit before calculating the transient response.
What is common to both thevenin and norton theorem?
To solve any D.C. circuit by using Thevenin Theorem,First of all load resistance RL is disconnected from the circuit and open circuit voltage across the circuit is calculated (known as Thevenin equivalent voltage)Secondly, the battery is removed by leaving behind its internal resistance. Now we calculate equivqlent resistance of the circuit ( called Thevenin equivalent resistance).Now we connect Thevenin Voltage in series with Equivalent resistance of the circuit and now connect load resistance across this circuit to calculate current flowing through the load resistance.Whereas in the case of using Norton theorem, we again remove the load resistance if any, and then short circuit these open terminals and calculate short circuit current Isc.Second step is same as in Thevenin theorem i.e. remove all sources of emf by replacing their internal resistances and calculate equivqalent resistance of the circuit.Lastly, join short circuit current source in parallel with equivalent resistance of the circuit. Now, we can calculate votage across the resistance which was connected in parallel with Isc.So, by knowing the open circuit voltage, we can calculate current flowing the resistance and on the other hand , by knowing the short curcuit current , we can calculate voltage across the resistance.
What is the use of thevenin's theorem?
By using Thevenin's theorem we can make a complex circuit into a simple circuit with a voltage source(Vth) in series with a resistance(Rth)
Norton's theorem is Converse of thevenin's theorem?

What are the disadvantages of using the thevenin theorem?
Thevenin's theorem is only valid for linear and bilateral networks.Practically, linearity of any circuit is over a certain range.Hence it is only valid for certain range.
What is norton's theorem?
Norton's theorem is the current equivalent of Thevenin's theorem.
What is Thevenience theorem?
I believe you are asking what is THEVENIN's theorem instead?
Conclusion about thevenin and norton theorem?
in conclusion,
How you calculate the polarity of voltage source across the resistor when two voltage sources are connected?
A: by using thevenin theorem
Thevenin's theorem is applicable to a network of?
thevenins theorem is applicable to network which is linear ,bilateral
Why does one replace voltage sources with a short circuit and current sources with an open circuit when using Thevenin's Theorem Long explanation please?
A: THEVENIN theorem simply is a way to simplify a complex input and resistance to a simple form. maybe you are confusing it with nodal analysis
How do you use thevenin's theorem to calculate current in resistors?
If this is an independent current source, it has to be disconnected.Independent voltage sources are replaced by a short-circuit.More about this at (see Related links):MasteringElectronicsDesign.com: How to Apply Thevenin's Theorem - Part 1, Solving Circuits with Independent SourcesandMasteringElectronicsDesign.com: How to Apply Thevenin's Theorem - Part 2.

Why thevenin's and norton's theorem are equivalent?
thevenin's and norton's theorems are equivalent.theoritically both can be derived from each other.if we consifder thevenin's equivalent circuit it consists of voltage source in series with thevenin's resistance .but an equivalent circuit can be obtained by replacing thevenin's voltage source by an equivalent current source with a resistance ioe thevenin's resistance in parallel which gives us norton's circuit.mathematicaaly both are interconvertible using ohm's law
Is Thevinin's theorem valid with the presence of dependent sources?
While some feel that Thevenin's (commonly misspelled as Thevinin's) Theorem is made invalid by dependent sources, rather than independent sources, most hold his theories valid. This is largely due to the superposition theorem, proven by combining Thevenin's theorem with Norton's.
