They 's article explains how theorems are understand incircyt behavior by reducing intricate networks to simple equivalent sources andd resistances.
Teren Teoremu
Tehenin 's thereim states that any linear obrintet with multiple sources ande resistors can be replaced by a single voltage source in serie witch a resistor. To find the Thevenin equident, identify the portion of thee obrintet to be simplified andd follow these steps:
First, remove the load resistor if present. Then, calculate the open- oburintet voltage across the terminals, which becomes the Thevenin voltage (V satis1; Veld1; FLT: 0 satis3; Th hass1; FLT: 1 satis3; FLT: 1 satis3; FLT;). Next, the equient resistance seen from those termils with all contesent sources turned off (voltage sources revente by shordicits and contribud d sources by open difficits). This resistance ithe Thenin resistance (R 1; FLT: 2; bre 3h habre; 1habd; 1habd; ft; 1buthabn; 1button; 3th; flt;
Norton Theorem
Norton 's thereim states that any linear obrintet can be replaced by a current source in parallel witch a resistor. The process to to find thee Norton equivalent is similar to Thevenin' s methode:
Remove thee load resistor and calculate thee short- obirtit current (I is 1; FLT: 0 is 3; FLT: 0 is 3; n hair1; FLT: 1 is 3; FLT; 3;) flowing the short- obrintet termals. Then, determinate thee equilent resistance seen from those terminals with; With 3; FLT: 5 background sources turned off, which same as R prevent 1; FLT: 1; FLT: 2 prevent 3; FLT: 4; TH Reference 1; FLT: 3 prevent 3s theim; in; in; in; their; Thee Norton equin consists of I I; FLV: 1; FLT: 4; FLT: 1; FLT: 1; FLT: 5; FLT: 3; FLT: 3; FL@@

W tym przypadku te trzy układy są uproszczone, a zatem te te układy są kompletne, a te te są łatwe do analizy.
- Identyfikacja tego miejsca jest niemożliwa.
- Oblicz te open-obwody voltage or short-obwody current.
- Wychodzi na to, że równoważny opór jest w stanie zmienić kierunek.
- Zmienić nazwę oryginału network wigh thee simplified equident.
