Note

Supposed you are given a circuit and asked to solve it using Superposition. And when you have shorted/open all voltage/current sources to find the contribution due to a particular source, you are allowed to use Thevenin and Norton analysis to solve the resultant circuit.

For example, in Question 1(b) in April/May 1998 Paper, when trying to find the contribution due to the current source, you will find that it is easier to solve by converting then current source and the parallel 1 Ohm resistor to a Thevenin equivalent.

Food for Thought

There was once a man who was learning archery from a great master.

One day, while practicing, the man’s arrow hit the bull eye of the target.  He was very excited and ran to tell the master.  The master took a look at the arrow and asked him if he knew how he had hit the target.  “I do not know,” said the man.

The master then told the man he have not mastered archery yet.  The man was discouraged but still continued practicing everyday.

Many days later, the man was able to hit the target whenever he shot.  He then asked the master to take a look.  Again, the master asked the man if he knew how the arrow hit the target.  The man said, “Yes, I do.”

“Good,” said the master,“You know archery now.”

It is not enough to hit the target.  It is understanding how that is the all-important.
