Thevenin Voltage vs Source Voltage
Formula
## Thevenin's Theorem Any linear circuit can be replaced by V_th in series with R_th. ### Formulas **V_th = V_s x R2 / (R1 + R2)** **R_th = R1 || R2 = R1 x R2 / (R1 + R2)**
Esempio Risolto
24 V source, R1 = 1k, R2 = 2k.
- 01V_th = 24 x 2000 / 3000 = 16.0 V
- 02R_th = 1000 x 2000 / 3000 = 666.67 ohms
Domande Frequenti
What is Thevenin's theorem?
Any two-terminal linear circuit can be replaced by a voltage source V_th in series with R_th.
How do I find V_th experimentally?
Measure open-circuit voltage across the terminals.
How do I find R_th?
Turn off all sources and measure resistance across the terminals.
