Best Answer

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.

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.

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.


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.


Can you apply thevenin's theorem in circuits having multisource?

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
