tailieunhanh - Lecture Electric circuits analysis - Lecture 19: Problems solving related to thevenin's theorem - Norton’s Theorem

Like Thevenin's theorem, Norton's theorem provides a method of reducing a more complex circuit to a simpler equivalent form. The basic difference is that Norton's theorem results in an equivalent current source in parallel with an equivalent resistance. Lecture provides knowledge of problems solving related to thevenin's theorem - Norton’s Theorem. | Problems Solving related to Thevenin's theorem Norton’s Theorem Lecture 19 Problems Solving-Thevenin's theorem Using Thevenin's theorem, find the voltage across R4.
