The current flowing through the load terminals Rl connected across any two terminals A & B of a linear, bilateral, active network is given by Voc/Rth + RL where VOC is the open circuit voltage across the terminals A & B & RL is the internal resistance of the network as viewed back into the open circuited network from AB deactivating all the independent sources.
Norton's theorem is the current equivalent of Thevenin's theorem.
I believe you are asking what is THEVENIN's theorem instead?
in conclusion,
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)
Yes, if the rheostats are replaced by three incandescent lamps, you can still verify Thevenin's theorem. Thevenin's theorem states that any linear circuit can be replaced by an equivalent circuit consisting of a voltage source and a series resistor. By analyzing the behavior of the circuit with the incandescent lamps, you can determine the Thevenin equivalent circuit and verify the theorem.
thevenins theorem is applicable to network which is linear ,bilateral
find current throrgh RL by using menemims
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. Nested Thevenin Sources Method
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.
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.
yes. its trickier but it works fine.
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
