What is Source transformation: Definition and 24 Discussions
Source transformation is the process of simplifying a circuit solution, especially with mixed sources, by transforming voltage sources into current sources, and vice versa, using Thévenin's theorem and Norton's theorem respectively.
My work seems to be wrong somehow since my answer is wrong, and I need your help to find out which part is going wrong for me :/

(10/7)/(10/7+7) = 0.7627A, which is not the answer.
May I consult where is the problem in solution? THanks

Hi.i know that a ideal current source has infinite resistance and it supply's constant current to aload connected across it. The current source doesn't have the infinite resistance in series to it but in pparalle. All is well until I think of this Norton's Therom. When we transform a voltage...
Hey guys, i did this source transformation as an alternate method to find the transfer function of a circuit, however I am getting a different transfer function of 2/(2s+(s+3)(s^2+1)) to the solution in the following image. Any help would be really appreciated :)

1. Just to clarify, when different voltage sources are in series you pick the smaller one?
2. First step, they turned the 1A and 2ohm into 2V, why does the resistance disappear? Then between the last two steps the 12/7 ohm resistance remains with 18/7...
