Summary To find Thevenin’s or Norton’s equivalent: 1. Identify the load resistor (or the resistor across which the equivalent needs to be determined), and remove it. 2. Find the open circuit voltage, V oc , across the output terminals (for Thevenin’s), or the short circuit current, I sc (for Norton’s). Set V oc = V th , or I sc = I N 3. For Rth or RN (remember Rth = RN): Remove all independent sources – short voltage and open current sources Find equivalent resistance between output terminals

Unformatted text preview: In case there are dependent sources, use test voltage method. Some tips. When only dependent sources are present: 1. Vth = 0V 2. Rth : negative Summary Using maximum power transfer theorem: 1. Usually you need to find thevenins equivalent because when RL = Rth, there is maximum power transfer. 2. Identify which resistor is the load. 3. Find the Thevenins equivalent for the rest of the circuit. 4. Maximum power Pmax = V th 2 /4R th...
