Methods of Analysis ENTC 210: Circuit Analysis I Rohit Singhal Lecturer Texas A&M University
Voltage Sources Two voltage sources of different ratings may not be connected in parallel. Why? Series operation, however, is permitted.
Current Sources Two current sources of different rating may not be connected in series. Parallel operation, however, is permitted.
Source Characteristics Voltage Current
Source Characteristics Voltage Current Current Source Voltage Source
Current Source A current source determines the current in the branch in which it is located. The magnitude and the polarity of the voltage across it depend on the complete network.
Source Conversion Source conversions are equivalent only at the external terminals
Question on Source Conversion!
Current Sources in Parallel
Current Sources in Series? No way.
The two Approaches already learnt! Reduce and Return Approach! Simplest technique Does not apply to more complex circuits. Current Loop Method Also known as “Mesh Analysis”
