Question

You have to use superposition. I don't get how to calculate all of the different voltages and currents separately with this method.

1. Use superposition principle for the circuit in Figure 1 to calculate components of Vi, V2, Vs, V4and Vs due to each source acting alone, and record your results in Table-I. Note that Vii is the component of Vi due to Vsi acting alone: Vi2 is the component of Vi due to Va acting alone, etc. Similarly, calculate components of Ii, I2, , Iand Is due to each source acting alone and record your results in Table -I 2. Complete Table I by calculating the actual values of Vi, V2, Vs, V4and Vs, and, 2, Is, l4 and Is when both Vsi and Vsz are active (ON).

Explanation / Answer

you can not find voltages and current without the values of resistors..

here i m giving the procedure of superposition theorem to solve this problem.

1. Consider the various independent sources in a given circuit.

2. Select and retain one of the independent sources and replace all other sources with their internal resistances or else replace the current sources with open circuits and voltage sources with short circuits.

3. To avoid confusion re-label the voltage and current notations suitably.

4. Find out the desired voltage/currents due to the one source acting alone using various circuit reduction techniques.

5. Repeat the steps 2 to 4 for each independent source in the given circuit.

6. Algebraically add all the voltages/currents that are obtained from each individual source (Consider the voltage signs and current directions while adding).
