1.Put a short circuit instead of voltage source 1 and find what you want with taking direction of current in that element(ris.ind.cap.)
2.puta short circuit instead of voltage source 2 and find what you want with taking direction of current in that element(ris.ind.cap.)
3.add current 1 and 2 for any element.

Is the superposition theorem applicable to non linear network why?
Yes, superposition theorem holds true in AC circuits as well. You must first convert an AC circuit to the phasor domain and the same rules apply.
Theory of superposition theorem?
Superposition theorem is one of those strokes of genius that takes a complex subject and simplifies it in a way that makes perfect sense. A theorem like Millman's certainly works well, but it is not quite obvious why it works so well. Superposition, on the other hand, is obvious.The strategy used in the Superposition Theorem is to eliminate all but one source of power within a network at a time, using series/parallel analysis to determine voltage drops (and/or currents) within the modified network for each power source separately. Then, once voltage drops and/or currents have been determined for each power source working separately, the values are all "superimposed" on top of each other (added algebraically) to find the actual voltage drops/currents with all sources active.
Analysis of digital and analog circuit?
Analog circuit continuous uses the time voltage and currents while digital circuits are sometimes called the on/off and high/low control of voltage in circuits.
Conclusion about thevenin's theorem?
Thevenin's theorem is a basic equivalence principle for circuit design. It can simplify a very complex circuit to a very simple equivalent. This is done by finding the Thevenin Resistance as well as the Thevenin voltage and current. Once these are known, the equivalent circuit is simply a voltage source in series with a resistance.
What is common to both thevenin and norton theorem?
To solve any D.C. circuit by using Thevenin Theorem,First of all load resistance RL is disconnected from the circuit and open circuit voltage across the circuit is calculated (known as Thevenin equivalent voltage)Secondly, the battery is removed by leaving behind its internal resistance. Now we calculate equivqlent resistance of the circuit ( called Thevenin equivalent resistance).Now we connect Thevenin Voltage in series with Equivalent resistance of the circuit and now connect load resistance across this circuit to calculate current flowing through the load resistance.Whereas in the case of using Norton theorem, we again remove the load resistance if any, and then short circuit these open terminals and calculate short circuit current Isc.Second step is same as in Thevenin theorem i.e. remove all sources of emf by replacing their internal resistances and calculate equivqalent resistance of the circuit.Lastly, join short circuit current source in parallel with equivalent resistance of the circuit. Now, we can calculate votage across the resistance which was connected in parallel with Isc.So, by knowing the open circuit voltage, we can calculate current flowing the resistance and on the other hand , by knowing the short curcuit current , we can calculate voltage across the resistance.
What is the superposition?
This theorem is used to determine the value of current in specific branch of a multi voltage source circuit .
Is super position theorem used for power calculation?
The superposition theorem (not 'super position'!) is used to solve complex circuit -typically a load with two voltage sources. It enables the currents through, and the voltage drops across, the various components to be calculated and, therefore, the power of each component can be determined.
What is the use of superposition theorem?
superposition can find the voltage and current effect of each source to a particular branch of the circuit and we can calculate the total effect of the sources to know the effect of the total sources to that branch

What is the use of thevenin's theorem?
By using Thevenin's theorem we can make a complex circuit into a simple circuit with a voltage source(Vth) in series with a resistance(Rth)
What is the voltage divider theorem?
it is aa linear circuit that produces the output voltage from the fraction of its input. It is also known as potential divider.
How do parallel circuits use current and voltage?
Kirchoff's voltage law: In a series circuit, the signed sum of the voltage drops around the circuit add up to zero. Since a parallel circuit (just the two components of the parallel circuit) also represents a series circuit, this means that the voltage across two elements in parallel must be the same.Kirchoff's current law: The signed sum of the currents entering a node is zero. In a series circuit, this means that the current at every point in that circuit is equal. In a parallel circuit, the currents entering that portion of the circuit divide, but the sum of those divided currents is equal to the current supplying them.
Why during measurement the measured voltage and currents have negative sign?
Because of the polarity of the circuit. The signs of measured current and voltage depends on the direction of the current and voltage.
What is the Superposition Theorem for an Electrical Network?
superposition therorem states that in linear network containning more than one source of emf the resultant current in any branch is the algebraic sum of the current that would have been produced by each source of emf .taken sepertely with all other sources of emf replace by their internal resistance ........... that is called superposition theorem ..
What are the applications of thevenin's theorem?
in simplifying complex circuits and for different loads this theorem proven very useful
Analysis of digital and analog circuit?
Analog circuit continuous uses the time voltage and currents while digital circuits are sometimes called the on/off and high/low control of voltage in circuits.
