Norton's Theorem: Current Through Load & Dependent Sources

[ranju]

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??

 

[MrSparkle]

you aren't deactivating the sources. You are solving the circuit, which may include deactivating the independent sources one at a time (superposition)

 

[ranju]

what is the reason of Isc or shortcircuit current to be zero?

 

[MrSparkle]

it shouldn't be zero except in a few special cases.

 

[ranju]

n what are those spcl cases?

n what are those spcl cases?

from PF guidelines:

Pay reasonable attention to written English communication standards. This includes the use of proper grammatical structure, punctuation, capitalization, and spelling. SMS messaging shorthand ("text-message-speak"), such as using "u" for "you", and "please" for "please", is not acceptable.

it shouldn't be zero except in a few special cases.

And what are those special cases?
