Final answer:
Thevenin and Norton equivalents are examples of terminal equivalency and can be derived from each other using source conversion. These concepts work only for linear circuits.
Step-by-step explanation:
Thevenin and Norton equivalents are examples of terminal equivalency and can be derived from each other using source conversion. These concepts work only for linear circuits. Terminal equivalency means that the Thevenin and Norton circuits have the same equivalent voltage source and equivalent resistance when viewed from the load terminals. Source conversion allows us to convert between Thevenin and Norton circuits by simply adjusting the values of the voltage source and the resistance.
