Problems and Solution Sheet On Network Theorems

Problem Sheet On Network Theorems:

In this post i am uploading the problem sheet on network theorems. these questions i have taken from the text book fundamentals of electrical circuits by Sadiku we should be thankful to sir for the great work because we can find so many problems on each and every concept and also i am uploading solutions to some problems from the sheet.

you can see and if there any mistake please let me know i will correct my self and remaining problems you can do on your own. if you are finding any difficulty post a comment as question number we can discuss.

Network Theory Lec-17(a): Network Theorems

Network Theory Lec-17(a): Network Theorems

   In this lecture , i have discussed the network theorems i.e superposition theorem, Thevenin's and Norton's theorems like their statement and how to find the response in a single branch using three theorem and also discussed their limitations.
   In thevenin's theorem how to find thevenin's voltage and thevenin's resistance in three cases
       When
1. only independent sources are present
2. independent and dependent sources are present and
3. only dependent sources

Solutions to Problems on Systems

Solutions to Problems on Systems:

Hai every one in this post i am giving a link to a PDF file which contains solutions to problems on Systems, i.e how to identify the properties of systems like linearity, time invariant, stability, causality, memoryless and invertibilty-inverse systems.

If you are having any difficulty while solving problem or with my solution please give a comment. we discuss and solve them once again because every concept should be clear while preparing for GATE
