![]() ![]() Till now we have discussed the basis to determine the response of any network using superposition theorem. Then the overall current can be determined. So, once the current through a particular branch is obtained by considering individual sources. We know according to superposition theorem, the overall current flowing through branch XY is equal to the summation of current through that particular branch, by the action of both the individual sources. Now, again considering both the two meshes of the above network and applying a network reduction method, the current through branch XY can be obtained given by I XY ᶦᶦ. While V 2 is active source for the next condition. In a similar way, for the next case, the source V 1 is to be replaced by its internal impedance or short circuit. So, by using network reduction technique the current through branch XY i.e., I XY ᶦ can be calculated for the independent source V 1. This is clearly shown in the figure above, The figure below shows the representation of activation of V 1,Īs we don’t know the internal impedance of V 2 thus it gets replaced by a short circuit. So, applying superposition theorem, first the voltage source V 1 is activated and V 2 is changed by its internal impedance. Here, as we can see that the network has 2 voltage sources V 1 and V 2 along with 3 resistances R 1, R 2 and R 3.Ĭonsider here that through superposition theorem we have to determine the current through branch XY. Once, the respective response is obtained for each individual source, perform the summation of all the responses in order to get the overall voltage drop or current through that element in the circuit.Ĭonsider the figure below, that shows the illustration of superposition theorem.Now, the next step is applying a network simplification approach and evaluating the current flowing through or voltage drop across a particular element in the network.įurther, the same approach of considering a single source and determining the voltage or current through the element is done for all the other sources separately.However, except the selected source, necessarily all the other sources must be replaced by their respective internal impedance. Among the various sources in the circuit, any one of the sources can be considered first. The first step is the selection of one of the sources among the multiple sources present in the bilateral network.Now, let us proceed further to know what are the steps that one should follow in order to apply superposition theorem? Steps to apply Superposition Theorem ![]() ![]() Thus at the time of evaluating the voltage or current through the circuit element, the voltage source to be replaced is short-circuited and the current source is open circuited. Basically, when we apply superposition theorem, the voltage and current sources are considered to be ideal. ![]()
