As far as its appearance from outside is concerned, any two terminal network of resistors and energy sources can be replaced by a parallel combination of an ideal current source isc and a resistor r, where. 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. Thevenin theorem, thevenins theorem solution example. Superposition problem with four voltage and current sources. 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.
Thevenin s theorem circuit with an independent source. Calculate the output voltage, v, when in open circuit condition no load resistormeaning infinite resistance. The relationship f x between cause x and effect y is linear if f. Nortons theorem maximum power transfer theorem supernode circuit analysis thevenin s theorem may be stated below. Superposition method circuit with dependent sources. While solving these example we are assuming that you have knowledge of thevenin s theorem. Equation 1 in the diagaram expresses an external voltage v y. 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. A few examples are presented after this page to illustrate the use of thevenins theorem. 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. Thevenins theorem example with solution electronics.
