Norton Resistance
Norton resistance is a method for simplifying linear circuits, which is used to study the behavior of the circuit. It is also used to calculate the current flowing through a specific branch of the circuit.
Shorting and Opening of Sources
Shorting and opening of sources are the two ways to simplify a circuit. When a voltage source is shorted, it is replaced with a wire. Similarly, when a current source is opened, it is replaced with an open circuit.
Option C
The correct answer to the question is option C, which states that Norton resistance is found by shorting all voltage sources and opening all current sources.
Explanation
Shorting all voltage sources and opening all current sources help to simplify the circuit, which makes it easier to calculate the Norton resistance.
In this method, all the voltage sources in the circuit are replaced with a short circuit, which means that the voltage across them is zero. Similarly, all the current sources in the circuit are replaced with an open circuit, which means that the current through them is zero.
This simplification helps to calculate the Norton resistance, which is the equivalent resistance of the circuit when all the sources are replaced with a current source.
Conclusion
Norton resistance is an important concept in electrical engineering, which is used to simplify and analyze linear circuits. The method of shorting all voltage sources and opening all current sources helps to simplify the circuit, which makes it easier to calculate the Norton resistance.
