To verify kirchhoffs voltage law kvl and kirchhoffs current law. To measure the load voltage and load current from the given network. Thevenins theorem as applied to the dc network ckt may be stated as the current flowing through a load resistance rl connected across any two. The discussion below gives a bit more detail about the procedures of this experiment. Calculate the output current, i ab, when the output terminals are short circuited load resistance is 0. Create the actual circuit and measure the current across the load points. The experiment that follows is carried out to determine the thevenin s theorem experimentally. Thevenin s theorem is an equivalence principle in circuit theory. Any twoterminal linear bilateral dc network can be replaced by an equivalent circuit. Create the thevenin s equivalent circuit by first creating the equivalent voltage source and equivalent resistance and then measure the current across the load using an ammeter. 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.
Calculate the output voltage, v, when in open circuit condition no load resistormeaning infinite resistance. Thevenin s theorem and its application by g r sinha 9 th june, 2017 thevenin s theorem thev enin s theorem stat es that a linear an d bilater al netwo rk can be. A linear active network consists of independent and dependent voltage and. 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. Thevenins nortons and maximum power transfer theorem. Understand and gain knowledge about circuit laws and theorems. Laboratory manual electrical circuits and simulation 1 department. Research the intended purpose of thevenin s and nortons theorems. 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. Follow the experiment steps from 1 to 10 on pspice and note the observed results to your prelab report which will be submitted.
Thevenin theorem, thevenins theorem solution example. Circuit used to study dc nortons theorem is shown in figure on nv6509a kit. For example, when a battery is charged, it absorbs energy which gets stored within. The power transferred from a supply source to a load is at its maximum when the resistance of the load is equal to the internal resistance of the source. Nortons theorem maximum power transfer theorem supernode circuit analysis thevenins theorem may be stated below. Verification of thevenin s theorem using the simulator, step1. To verify the superposition theorem for the given circuit.
