THE´ VENIN’S AND NORTON’S THEOREMS

THEVENIN’S AND NORTON’S THEOREMS

 

 

A linear, active, resistive network which contains one or more voltage or current sources can replaced by a single voltage source and a series resistance (The´venin’s theorem)or by a single currentsource and a parallel resistance (Norton’s theorem). The voltage is called the The´venin equivalentvoltage, V0, and the current the Norton equivalent current, I 0. The two resistances are the sameR0. When terminals ab in Fig.  are open-circuited, a voltage will appear between them
