CONSTRUCTION, CALCULATION AND
VERIFICATION OF SUPERPOSITION THEOREM
CIRCUIT 1:
SIMULATION:
PROCEDURE:
1. MULTISIM:
This Lab Report is accompanied by Simulation software, known as
“Multisim” software.
Multisim is the most complete and robust circuit design and
simulation suite available.
Install the Multisim Software and then open it to start Circuiting.
2. INTERFACE:
The moment you’ll open it, there will be a blank Interface (Circuit
Window) shown to you which look alike Bread Board. This
interface allows you to embed the electrical components into it.

3. APPARATUS:
After that, we will select two DC Sources of the range 8 volts and
4.97 volts, from the “place source icon” on the Toolbar. The value
of DC Voltages can be altered by double clicking on the DC source.
After that, we will select resistors from the “place basic icon” of
the Toolbar. The values of resistors can be changed by double
clicking on the resistors.
We will take the resistors’ values as:
R1= 9.90,
R2= 5.54
R3= 12.03.
4. CONSTRUCTION:
Now, we will arrange the circuit as shown in the figure. In order to
change the directions or position of the components, we have to
right click on that component to see these options.
All the components will attach to each other by conducting wires.
These wires can be drawn by clicking any of the components’
terminals and dragging it to the other components’ terminal.
5. MULTIMETERS:
After that, we will add the Multi-meters in the circuits from the
Toolbar at the right side of the Circuit window. We will take one
Multi-meter from the Toolbar. It will be placed parallel to the
node A. One probe of the Multi-meter will be connected to the
respective Node and the other probe will be at Zero Potential
(Ground).
The parameters you want to measure by the multi-meters can be
selected by double clicking on the Multi-meter.
6. REARRANGEMENT OF SOURCES:
We will first find voltage at Node A by including both voltage
sources in the circuit.
We will again find the voltage across Node A by shorting one
Voltage source each time.
We will find the effect of individual and combine voltage sources
on the Nodal Voltage V
a
.

7. COMPILATION:
After designing our Simulated Circuit, we will press the “Run
Simulation” button marked on the Toolbar at the top, or turn the
Switch On at the top Right Corner of the Circuit Window.
This process will allow both the Multi-meters to show the values
of their respective parameters.
8. RECORDING:
At the end, we will record all the readings and write it in the
Calculations table.
