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.

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.

yes. its trickier but it works fine.
in simplifying complex circuits and for different loads this theorem proven very useful
The Maximum Power Transfer Theorem is not so much a means of analysis as it is an aid to system design. The maximum amount of power will be dissipated by a load resistance when that load resistance is equal to the Thevenin/Norton resistance of the network supplying the power.
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 the current equivalent of Thevenin's theorem.
I believe you are asking what is THEVENIN's theorem instead?
in conclusion,
A: by using thevenin theorem
thevenins theorem is applicable to network which is linear ,bilateral
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

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
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.
