Document Summary
Step 1: leave one source on , turn others off (set them to zero) ** can"t solve for nonlinear things like power. Example: find (the voltage at the extraordinary node) Superposition says that because this circuit is linear, we can solve for vx by combining these three equations. Method 1: find, find, solve: (short circuit) (open circuit) Method 2 (new): find either or, set all sources to 0, simplify to a single resistor which will equal the thevenin resistance. Step 2: add an external source to find. Step 3: cancel where is the external source you added (which will out) and is the current running through it. ** this method works with both independent and dependent sources example: mesh 1: mesh 2: aux: now add in an external source and set independent ones to zero mesh 1: mesh 2: mesh 3: Maximum power transfer theorem find the resistance such that it maximizes the power through it.
