and then just replace a thevenin equ that you'll get with NortonsNorton's theorem is a circuit analysis technique that allows us to simplify complex circuits into a single current source and a parallel resistance. This theorem is named after its inventor, Edward Norton, and is often used in electrical engineering and physics.
Norton's theorem is based on the idea that any linear circuit can be represented by a current source and a parallel resistance, while Thevenin's theorem states that any linear circuit can be represented by a voltage source and a series resistance. Essentially, Norton's theorem is the current equivalent of Thevenin's theorem.
Norton's theorem is useful when analyzing complex circuits, as it allows us to simplify the circuit and focus on specific components. It is particularly helpful in solving for current and power in a circuit.
The Norton equivalent current is equal to the short-circuit current of the original circuit, and the Norton equivalent resistance is equal to the resistance seen from the two terminals of the circuit when all independent sources are turned off.
No, Norton's theorem can only be used for linear circuits. Non-linear circuits do not follow Ohm's law, which is a fundamental principle for Norton's theorem to hold true.
