Introduction 

What is Superposition theorem?



When it can be applied?

Introduction

 If there is more than one source in an

electric network, the response (voltage

or current) can be determined by

considering one source at a time.



The total response is the algebraic sum

of the individual responses.

 While determining the responses with a

particular source, all other sources have

to be deactivated (voltage sources

replaced by short circuits and current

sources by open circuit).

Circuit Diagram

Procedure

 (^) Construct the circuit on Multisim Electronics Workbench.  (^) Put the meters in the appropriate places to read voltages across and currents through each resistor.  (^) Run the simulation. Record all the voltages and currents in the circuit and enter them in Table

 (^) You can use ammeters for current measurements, voltmeter for voltage measurements or multimeter for both.  (^) Note the current directions and voltage polarities shown in Figure.

Procedure



Remove the 5-V source from the

circuit. Replace it by a short circuit.



Run the simulation. Measure the

voltages and currents and record in

Table 2.

Procedure

 (^) Put the 5-V source back to the circuit. Remove the 10-V source and replace it by a short circuit.  (^) Run the simulation. Record all the voltages and currents in the circuit. Enter them in Table 3.
