Electric Circuits and Networks

5.10 SUMMARY

• This chapter dealt with some circuit theorems that form an indispensable tool set in circuit analysis. Many of them were stated for linear time-invariant memoryless circuits. However, they are of wider applicability and will be extended to circuits containing inductors, capacitors and mutually coupled inductors in later chapters.
• Superposition theorem is applicable only to linear circuits. It states that ‘the response of any circuit variable in a multi-source linear memoryless circuit containing n independent sources can be obtained by adding the responses of the same circuit variable in n single-source circuits with i^th single-source circuit formed by keeping only i^th independent source active and all the remaining independent ...
