Solved problems on nortons theorem q1 find the nortons equivalent circuit across ab terminals for the circuit shown in figure 14 star delta transformation solved problems solved examples on stardelta transformation q1. Superposition states that the voltage across or current through an element in a linear circuit is the algebraic sum of the voltage across or currents through that element due to each independent source acting alone. Thevenins example summary 1 the graph shown in the right hand side gives the final result for thevenins theory. A is more suitable for graph containing denpendent source. You should do a bunch of these to get ready for quizzes, exams, etc. The circuit from figure 1a can be reduced to its thevenin equivalent circuit in four. By using this theorem we can reduce the complexity of any circuit network and can simplify if only two criteria fulfilled 1st the network is linear and 2nd is bilateral.
Find the values for thevenin and norton equivalent circuit with respect to the terminals a and b. Thevenin theorem, thevenins theorem solution example. Find the value of the open circuit voltage, voc and thevenin resistance, rth. The circuit shown in figure 1b is the thevenin equivalent circuit of the circuit shown in figure 1a. Thevenin theorem is used in nortons theorem to obtain nortons equivalent circuit. Then find the current through rl 6, 16, and 36 example 4. Nortons theorem maximum power transfer theorem supernode circuit analysis thevenin s theorem may be stated below. An easy way to find for circuits without dependent sources is to turn off independent sources and find. Any linear electric network or complex circuit with current and voltage sources can be replaced by an equivalent circuit containing of a single independent voltage source vth and a series resistance rth. It is also used in maximum power transfer theorem to find the equivalent resistance of the network. The main practical application of thevenin s theorem is to find the variation of voltage and power delivered to a variable load. This theorem is named thevenin s theorem on the name of a scientist thevenin, he fist apply this theorem to the analysis of a circuit. The thevenin theorem guarantees that, it is not saying that is the voltage across the load in the original circuit.
