Norton’s Theorem states that any linear two-terminal circuit can be replaced by a simple equivalent circuit consisting of:
A Norton equivalent current source (I<sub>N) in parallel with a
Norton equivalent resistance (R<sub>N).
This equivalent representation simplifies the analysis of circuits, especially for determining the current through or voltage across a specific load.
Circuit Diagram:
Consider a circuit consisting of:
Resistor R1 (1 kΩ) in series with R2 (2 kΩ)
A DC voltage source (15V)
The objective is to find the Norton equivalent across the terminals A and B where a load resistor (R<sub>L = 1 kΩ) is connected.\
