SUMMARY

Norton’s Theorem states that to find the current through a load in a circuit with dependent sources, one must short the load terminals and deactivate independent sources. However, the presence of dependent sources means that the current through the load will not necessarily be zero, except in specific cases. The discussion emphasizes that the short-circuit current (Isc) can be non-zero, and understanding the conditions under which this occurs is crucial for accurate circuit analysis.

PREREQUISITES
  • Understanding of Norton’s Theorem
  • Knowledge of circuit analysis techniques, including superposition
  • Familiarity with dependent and independent sources in electrical circuits
  • Basic concepts of short-circuit current (Isc)
NEXT STEPS
  • Study the implications of dependent sources in circuit analysis
  • Research specific cases where short-circuit current (Isc) is zero
  • Learn about superposition theorem applications in circuits with dependent sources
  • Explore practical examples of Norton’s Theorem in electrical engineering
USEFUL FOR

Electrical engineering students, circuit designers, and professionals analyzing complex circuits with dependent sources will benefit from this discussion.

for finding the current through the load we short the load terminals and deactivate the independent sources..but if there are dependent sources ..will the current become zero through the load...?? because its stated in my reference book..iof so.. what's the reason..?? being dependent source..how does it affect supplying current to the terminals??
 
Engineering news on Phys.org
you aren't deactivating the sources. You are solving the circuit, which may include deactivating the independent sources one at a time (superposition)
 
what is the reason of Isc or shortcircuit current to be zero?
 
it shouldn't be zero except in a few special cases.
 
n what are those spcl cases?

And what are those special cases?
