Simplifies complex circuits into single voltage source (Thevenin) or current source (Norton) for easier analysis. Equivalent circuits valid for load analysis.
الصيغة
Vth = Isc × Rth
دليل خطوة بخطوة
- 1Thevenin voltage: open circuit voltage at terminals
- 2Thevenin resistance: resistance seen with sources removed
- 3Norton current: short circuit current
- 4Norton resistance equals Thevenin resistance
- 5Vth = Isc × Rth
أمثلة محلولة
الإدخال
RTh=100ohm, VTh=10V
النتيجة
Thevenin equiv
أخطاء شائعة يجب تجنبها
- ✕Not properly calculating open circuit voltage
- ✕Forgetting to remove sources for equivalent resistance
أسئلة شائعة
When should I use Thevenin equivalents?
To analyze different load impedances without recalculating entire circuit.
Are Thevenin and Norton equivalent?
Yes; same underlying network; Thevenin more common for voltage sources, Norton for current.
