Solution: Step 1: First, let us find the current flowing through a circuit by considering only the 20 V voltage source . In simpler words, if a circuit has energy sources like dependent or independent current sources, and has a complex structure of resistances, then the whole circuit is representable as a circuit consisting the equivalent current source, the load resistance, and . Norton's Theorem Review General Idea: Norton's theorem for linear electrical networks, known in Europe as the Mayer-Norton theorem, states that any collection of voltage sources, current sources, and resistors with two terminals is electrically equivalent to an ideal current source, I, in parallel with a single resistor, R. In Thevenin theorem, we see that in any complex circuit sources are converted in single voltage source Vth with the Series resistor Rth. A highly valuable byproduct of Thevenin's and Norton's theorem is the technique of source transformation. Zeroing out a source means that independent voltage sources are . August 28, 2019 August 15, 2019. This voltage is known as Thevenin's voltage or ; open circuit voltage. It is known as Norton's equivalent circuit. In contrast to the Thevenin's theorem, Norton's theorem replaces the part of the circuit with an equivalent circuit that constitute a current source and a parallel resistance. 6 Repeat the last problem using Norton's theorem.
