That's Right! First Try to Under stand the subject.

Thevenin was a telegraph Engineer,and learnt from Helmholtz about Equivalent/Source Impedence and Equvalent Battery for any complex circuits,and used it.

Since then we are all using it,and even computers know to use it,but not like humen.

The humen who can use it and also the Nortons Equvalent circuits are called Electrical/Circuit Engineers.

I got my answers....on my own attempts..and yes one thing need to mention ..as I am new to this forum so I don't know What's the thing I have to post in thread thats why I posted only problems.Before posting this thread I attempts it 6 times..but on paper and I forget to post necessry formulae and attempts..:)
