Introduction In this lab, +e are #oin# to sol"e a resistor net+or usin# su$er$osition $rinci$les! The su$er$osition method is used to analy-e a circuit usin# one "olta#e or current source at a time! If the source is "olta#e source, it is re$laced by a short circuit! If the source is a current source, it is re$laced +ith an o$en circuit! Then the results are added as if the net+or is analy-ed simultaneously! Consider the resistor net+or in Fi#ure 1 belo+&
Fi#ure 1 Considerin# "olta#e source one by one, this net+or is e.ui"alent to the sum of the t+o net+ors in Fi#ure 2 belo+!
Fi#ure 2 Addin# the results from both net+ors +ill #i"e the total current or "olta#e throu#h the load! In the follo+in# e/$eriment +e +ill $ro"e the su$er$osition method!
